G6 owners rejoice! I found a cheap way to add a quality auxiliary input to a stock G6 headunit! I bought and installed a Scosche wired FM modulator and it works great! Basically you plug youre car's antenna into the Modulator, and the modulator into the headunit. Because it is hardwired, it allows for much better sound quality than a wireless transmitter. It isnt quite cd quality, but its pretty good considering the price.

How-To:

Several People expressed interest in the modulator, so i figured a how-to guide for the G6 couldnt hurt. First off, along with the modulator unit, G6 owners will need antenna adapters because GM vehicles use a micro antenna fitting (here is a link to the ones i got). You will need to remove a good portion of the dash to get at the back of the radio, so http://www.g6performance.com/phpBB3/viewtopic.php?f=29&t=5991 is an excellent tutorial (its a life saver).

After the dash is opened up, find a suitable place to install the modulator. I used double sided tape to stick it in with the fuse box (below and right of the radio). After the modulator is mounted, run the antenna hook-ups behind the radio, hook the modulator into the antenna and headunit using the adapters. Tuck the wires down behind the radio - dont worry, theres plenty of space.

You can see in the picture below were I located everything, and how I wired the power.
In the G6, the fusebox is located conveniently close to the radio, so running the wiring was a breeze.http://i56.photobucket.com/albums/g199/luckyedboy66/Fuseboxside.jpg

Now connect the black wire to the frame (see above, bottom right), [edit] and tap (or tuck under) the red wire to the A/C fuse so that it will cut power when the ignition is off. The modulator comes with a 2 amp inline fuse so you dont have to worry about burning it up.

Now that the antenna and power is hooked up you need to find a spot for the power switch and 1/8" mini plug. The unit comes with a nice little housing that can be stuck in a good location, but i wanted to hide mine, so i installed the power and mini plug in the top of the cubby just below the A/C controls. http://i56.photobucket.com/albums/g199/luckyedboy66/plateinstalled.jpg

http://i56.photobucket.com/albums/g199/luckyedboy66/Moddedplate.jpg

Now youre pretty much done, but before putting the dash back together, test the system to make sure it works! The modulator can be set to broadcast on 87.9 and 88.1 FM (if i remember right), so pick whichever you want to set the radio to. After youre satisfied that everything works, put the dash back together and youre done! Here are some more pics of the modulator and my finished product.

Thanks for reading :D! Let me know what you think and dont hesitate to ask questions if I didnt explain things well enough :glasses:

EDIT: I found that I was getting some interference when I cranked up the A/C. I looked an noticed that I had the wiring routed up against the A/C electric fan housing (behind the head unit), so I rerouted the wiring further away from it and the audio is clear.

Just ordered all the parts, should have them this week!

I was just wondering, what is the easiest way to pull off the dash around the deck?

Thanks :)

FM modulation...? :confused:

How much are all the parts?

Hmm, If you were to go through all that trouble, I would just put the hard wired version in.

mmm im not sure what you mean... it is hard wired. if you mean replacing the head unit, there are several reasons why i didnt: cost and loss of the computer display, mainly.

There's a kit that plugs into the 12 pin connector on the back of the radio. When you press the SRCE button under volume. It changes from Radio to CD to AUX if its plugged in.

Your route is cheaper, but you don't really rule out 100% static. If you pause the music some how and crank it up, you'll hear a hissing sound.

Does this method charge while playing? I have an older iPod and the battery is crap. But if I can find something that will connect via the dock connector and charge it while playing, that's a win.

when you go to order it it says it isnt meant for the g6

when you go to order it it says it isnt meant for the g6

This looks pretty cool and seems like a cheaper way to get an aux input rather than buying a new head unit. Has anybody ever gone this route with the G6 or installed it before?

Think that depends on if you have monsoon or not. they probably don't include the G6 because if its not the monsoon it won't work or something. People getting mixed up..

alright....well i got the monsson, maybe ill order it and make a weekend project out of it....now where to mount that huge box and inputs...?

Talked to the customer service at discount parts direct and here is the link for what would work for a 07 GT with monsoon and no xm

http://www.discountcarstereo.com/detail.aspx?ID=1246

From what i understand if your car totally doesnt have sat radio (what it works through, i think :confused:) then you have to go to the dealer and have them activate it....other wise looks like it should work fine, has a one year warranty and can be returned if it doesnt work. If you search "PXAMG operation in 2009 pontiac G6" on youtube they have a demo

Talked to the customer service at discount parts direct ...

if your talking about GMPARTSDIRECT.COM then I call BS.

They have no service. Thats how they are so cheap. ZERO customer service....

Oh wait a minute.....they dont have your money yet do they? Order and then call them and see how they treat you.

I freeeking hate them. They suck. The parts are cheap and good but if
you have a problem you are SOL. :mad:

Pay attention to the screen with small print that you have to hit accept to order. READ what it says. The cliff note version is:

"I give up all my rights and agree to get screwed and do not hold GMpartsdirect lible for anything they do"

Whoops... Meant discount car stereo heres the link....they're customer service has seemed very helpful so far
http://www.discountcarstereo.com/detail.aspx?ID=1246

Oh....nevermind. lol

well i ordered the device yesterday, shipped out today:D

I'll yet ya'll know when i get it and how it works

Received the product took apart the dash installed it and.....it didn't work. Turns out I have an 07 monsoon stereo without xm and the product needs the xm port to function (the rep gave me the wong info.) so looks like for my situation I would just have to go the route of getting a new headunit with an aux. If you like the look of this system and the fact that its cheaper than getting a new headunit, make sure your vehicle IS XM CAPABLE

RR,
oh no!! i was hopping for good news. Prior to reading your post i found this person who successfully install the PAC version of the pxamg in his 2005 G6
http://www.g6ownersclub.com/forum/showthread.php?t=3378&highlight=ipod+adapter (see post #4)

Mine (like yours) does not have XM and according to that website the xm port must be active or get activated by a dealer otherwise it will not recognize the adapter.
http://www.discountcarstereo.com/detail.aspx?ID=1246

did this not work despite having the dealer activate that port?

I'm curious to know what you did

I followed all of the instructions to the letter. But the problem was that since my car doesn't have the monsoon radio that is xm capable. Which means that my cars radio harness doesn't have the necessary 12 pin connector that is ain addition to the stereos 24 pin connector. This 12 pin connector is necessary for the product to work since this is the xm radio connector and the connector is that pathway that the system uses to create a glitch in the xm band that allows you to control your iPod through the stereo. So I found this out after I took the entire dash apart. And after that I made an appointment with Pontiac to try and activate my satillite radio port (they were going to charge me $34 because they weren't sure if it was going to work. However I was able to find out the afformentioned facts from the companys tech so I didn't have Pontiac take my money. In process my stereo f'ed up and started displaying "changer parked" and "calibrate" so I had to have Pontiac reprogram it. Bottom line if your stereo has xm or the capability and you have the guts to take the terribly designed dash apart this interface WILL work.

yikes....

hey that's me. Ya I bought my G6 then realized that i needed some form of tunes. I went out and tried all of those different FM transmitters and got fed up with them. I looked around and really my only option I found was this or buy a different head unit. So I said screw it I'll pay an arm and a leg for a cheap plastic box, tonnes of wires and a 5 cent circuit board. But it does give me good sounding tunes, and for that I am thankful. My only complaint is that it is quite expensive, and takes some fiddling with the ipod and connection to find a your songs. It has the capability to control the ipod from stereo however the display on the ipod is still far simpler and much faster.

so let me see if i got this right.... if i have a 07 G6, without the XM option on it, i can still get this and it will work, but i need to go to the dealer and have the sat. port activated?

If your asking about the uPAC-GM11b then the only requirements is that it is a monsoon stereo with the 'Band' button above the volume control. You can click on the link in my signature block for more info.

Yes and thanks for chiming in.
The website does say that the radio must have both a 12 & 24-pin connector. So i did a little research by looking at used radios for sale on fleebay. The radios i found without a P-TYPE button lack the 12-pin connector, and those with a P-TYPE button had both the 12 & 24-pin connector. This information may help to determine if the radio in your car is XM capable without having to remove it from the dash.


My radio does have a P-TYPE button so I'm confident it will work.
as for RedRocket, why not buy a used radio instead of trying to install an aftermarket one? My understanding it that you will have to buy a radio replacement adapter, dash kit etc. Those can be expensive.

I bought the PIE GM12-AUXV2 mentioned earlier in the thread to use in my 07 G6 GT Convertible, but have been unable to make it work.

I noted all of the comments about it needing to be a Monsoon with the XM radio port enabled (it is -- I can hear the prevew channel), but when I try to toggle to Aux by pressing seek up/seek down, it just seeks the XM radio up and down.

I've verified that I have 12V going to the unit, and the jumper is set to "XM".

Any other suggestions?

GM12-AUXv2 will not work in that vehicle because its a GM Class 2 adapter and your vehicles is GM LAN. Good news is that you will be able to use the PXAMG-GM3 mentioned in this thread without any issues.

As for the other post.. Monsoon has no relation to this system. As far as i know if the radio has a P-type button on the face it will have the two connectors on the back. You won't know if the radio is already programmed for XM until you connect it. The sure thing is that any radio with a P-type button is XM ready.

I installed the scosche modulato in my car last night and I dont have XM or monsoon or even the 12 pin port on the back of my radio and mine works great. this guide is a lifesaver. the only difference was that extended the wires so I could run my switch and input back into my center console where I had an OEM cutout for what I assume was a place for a cigarrette lighter. this guide was really a lifesaver.

Think that depends on if you have monsoon or not. they probably don't include the G6 because if its not the monsoon it won't work or something. People getting mixed up..


so, i´m confused, i `ve a 2005 G6 with a single CD monsoon stereo, do you think that the aux input adapter mentioned by our friend maykevin5 in http://www.discountcarstereo.com/detail.aspx?ID=446 could work for me?

i found this (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=120429702702&viewitem=&sspagename=STRK%3AMEWAX%3AIT) for us ipod/iphone users

'07 G6 Convertible, Monsoon, with XM on the radio and currently using XM.

So, I assume the PXAMG will work for mine?

Birthday's coming up soon...may have to buy a present to me.

Lets make this a sticky thread!

last weekend, i installed this on my ´05 G6 (w/ single cd Monsoon stereo) and worked like a charm, it also displays the ipod info. I took it to my car audio installer and it took him no more than 10 min. to install it. it was a clean install because the seller sends the adaptor with the harness right for our G6´s, also send me a RCA to 3.5 mm cable to connect it to the aditional RCA aux inputs that the adaptor has.

check it out:

http://articulo.mercadolibre.com.mx/MLM-32406681-adaptador-de-ipod-para-autos-gm-gmc-pontiac-cadillac-hummer-_JM


this cost me around 110 bucks plus 13 dlls of shipping in this bid.

Thanks for the guide and all the info, I'm going to try my own install. Thanks to all the people who post a lot of useful info on the G6 Forums, really helped me learn about the car and personalize it on a budget :)

I have a 2005 Pontiac G6 with XM, OnStar, and a single slot CD. Is it a Class II radio, allowing me to use the PIE GM12-AUXV2? Or is it a GM LAN?

Basicly, should this work?

I love this forum and all of you experts so I have a question... Have any of you determined if the PXAMG or the PAC uPAC-GM11B is the way to go for the aux/iPod? I am going to buy one of them but since they are both over a hundred bucks, I wanted some input as to which product you guys thought was the better choice. Thanks for any opinions that you may have.

Don't know much about the PXAMG, but I know in order to get HD you have to have a HD tuner to connect to it. Also don't know if you can control the Ipod like you can with the UPAC. I'm sure you prob can, but never used it. The install for the UPAC was pretty simple.

If you are considering either the PXAMG or uPAC and will have a device running iOS4 that you want to use with it (iPhone 4, iPad), you may want to hold off on buying a unit for a little bit. PAC just released a hardware and firmware update and if you have one of the older units (i.e. you buy one today) it is $30 for the hardware update to work properly with the new OS.

I just got my unit last Friday and made an exchange for the proper cable on Tuesday. Wish I had known about the update sooner as I was at their SoCal office and could have gotten it taken care of.

~ MattInSoCal

Thanks for the advice. I am going to go with the UPAC unit. From what I have seen, the install seems pretty easy. I know I saw a guide on here to take the dash apart. I will find that and use it and things should then go smoothly.

Another option to add an Aux-in would be to splice into the CD or Radio audio pre-amp line. I did this on my '00 Grand Prix GT after following http://www.clubgp.com/newforum/tm.asp?m=3273349&p=1&tmode=1&smode=1, it worked great only down side was that a CD had to be in the drive for it to be activated.

I went the basic FM Modulator route. Had it installed by Future Shop for about $100 all in for parts and labour. I must say though, the audio quality is pretty inferior... still better than your basic fm transmitter but not CD quality. Living in an urban area every single fm frequency has a strong radio station attached to it as well, which makes it harder to get a clear signal. I'd replace the head unit, but they were nice enough to stick all that valuable information like the trip computer, fuel economy etc into the stock head unit instead of the instrument cluster.

I can think of a few possibilities. The FM modulator they installed is crap. It was installed wrong. It is broken.

When properly installed, an FM modulator in your car is like someone using a megaphone next to your ear, while the FM stations are like someone a block away using their hands to amplify their voice. If the megaphone is on, you can't hear the guy a block away, but when it is off you can. That's the simplified version of how it works. Besides that, when the modulator is turned on it is supposed to disconnect the antenna, so unless you were within 6 blocks of the transmitters you wouldn't hear them.

Mind you, you shouldn't expect the sound to be CD quality, but it shouldn't be any worse than any FM station you listen to.

I'd go back to the shop and complain.

Part of my professional geekiness involves knowing an awful lot about how radios work.

If you really searched everywhere you would have found the answer; it's out there and not at all difficult to find.

First, start at the PAC Audio site (http://www.pac-audio.com/productSearch.aspx?Make=Pontiac&MakeId=28&Model=G6&ModelId=1248&Year=2006&YearId=17). Then, choose the adapter that has the features you want. They will all work fine, but each has slightly different features and capabilities. Next, you might want to price-shop a bit as PAC sells at the MSRP. Finally, you might want to have a look the post I linked in the reply above yours (http://www.g6ownersclub.com/forum/showthread.php?p=49738#post49738).

nvm I looked some more and found out about the uPAC-GM11b on another thread. I didnt see at the pac site there was a ipod solution area. I was just looking in the aux solution area which didnt have this one for some reason. You would think they would've put that all together. Thanks though!

Hey guys,

So instead of buying a $190 addon for this stereo unit, I decided to hack up an aux cable on my own. After hours of messing around with the XM addon port, I figured out that I can use the pins right below the XM ones for a second AUX. So I hacked up my aux cable, and on the bottom row, pins 2-4 I have black, red, and ground. Well this absolutely works the IPhone sounds GREAT coming through the newly added AUX.

So here's my dilemma, where I was hoping for a little more expertise to help out. I am looking to retain the XM also. So in pins 2-4 on the top row, I have maintained the XM connections. If i connect either the top row XM or the bottom row AUX connectors, everything works great. When I connect all 6 wires, the sound goes all crazy. I believe it is because, even though I have them as separate pins on the back, in actuality the stereo is sharing their ground. If I remove either ground, the problem goes away, or if I leave both grounds in and remove one set of L/R the problem goes away.

I was really hoping to avoid having to put a physical switch in. What I'd like to be able to do is set the XM to 000 (radio ID) and use the aux cable, and then just use the XM when nothing is going through aux. I'm so close to making this work if not for the shared ground. Right now I'm thinking I have to put a spst switch on the ground (or switch the L/R, one or the other) and hide it in the glove box or somewhere. Like I said I REALLY don't want to have a manual switch. Can anyone think of an alternative, or something I may be doing wrong?




----

PS. anyone who doesn't care about the XM but has an XM port should be able to use the above procedure ignoring the existing XM connection for about $15 in radioshack materials.

Good news everyone. After days of playing around with the stereo, I managed to build my own AUX port for the G6. Below is my attempt at a how-to.

A few notes first.
1. This will only work for G6 stereos that are XM ready. This means that the stereo has a Band button on it. The actual XM module is not required. From reading earlier posts, you may need to have your stereo activated if the stereo has not actually used the XM feature. I did not have to do this, as I was able to tune into the XM preview channel.

2. If you do not care about retaining XM functionality, you can skip the step regarding adding a toggle switch and wire the aux wires directly to the XM port (or even splice them into the factory XM harness if it is there)


-----
Total cost was approximately $30 for materials. Depending on materials and how much of this you are implementing, costs could be higher and lower.

Materials Used.
-Audio Extension Cable (I used 16 ft and cut in half)
http://www.radioshack.com/product/index.jsp?productId=2103868

-Butt Connectors - used to connect audio wires to stereo pins (I used the smaller green/lime ones)
http://www.radioshack.com/product/index.jsp?productId=3004022

-crimp on connectors - used for switch instead of soldering
http://www.radioshack.com/product/index.jsp?productId=2103313

-DPDT rocker switch - to switch back between XM and AUX
http://www.radioshack.com/product/index.jsp?productId=2062521

-Tap In Connectors - to tap into factory XM harness
http://www.radioshack.com/product/index.jsp?productId=2103500

-Pliers
-Stepper drill bit for hole for switch
-wire strippers
-audio cable wire


Ok, now we're ready to begin

1. Remove stereo http://www.g6ownersclub.com/forum/showthread.php?t=1044

2. If you are not worried about retaining XM capability, skip to step #12 . Tap into the 3 wires from the XM harness. There are only 3 wires, so add the tap and an additional wire, and clamp them down with your pliers. From left to right, the wires are ground, left, right. I used Black, Green, and Red to help me remember which wires are which (I also tested with a laptop panning the balance when completed just to make sure this was correct. I recommend you do the same)
http://imgur.com/hMDIj.jpg

3. Add crimp wire connectors to the end of the left and right wires. Place the crimps on the wire and squeeze it tight to secure it.

4. Determine where you will place your switch, and mount appropriately. If you are mounting somewhere where it will be difficult to attach wires, you may want to skip ahead and attach the wires to the switch before you mount. I mounted mine on the top of the wallet compartment under the stereo. Almost completely hidden yet very easy to get to. First drill a starter hole. Then use the step bit to drill a bigger hole until the hole is the appropriate size to mount your switch. Then mount it! (below image is upside down)
http://imgur.com/5gX41.jpg

5. Trim the audio wire to the length you want. You need to determine where you want to run your aux cable to, and how you want it mounted. I ran mine to the console box, and I am using the male connector. I cut mine down to 8 ft, using the male connector side

6. Strip the main wire cover on the aux wire. There will be 2 or 3 wires inside of the main tube cover. Red, black (or white), and bare wire usually. this is your right, left, and ground. Strip these wires also.

7. add the crimp on connectors to the red and black wires on the aux cable. place the crimps on the wire and crimp them with pliers or crimpers.

8. Connect these wires to the bottom set of connectors on the rocker switch. You may have to either tighten or loosen the crimp connector to make sure it fits snug on the switch connector.

9. Connect the wires that we tapped into the xm connector into the top 2 connection on the switch. Match the left and right (red and green) with the left and right on the aux. That is, connect both greens on the left side of the switch, and both reds on the right or visa versa.

10. Cut two 1ft wires (i used red and green again) and strip both sides of the wires. On one side, put the crimp connectors again.

11. Connect the crimp connector side of the wires to the middle of the rocker switch. Again, be consistent with the left and right. The final product should look like this.

12. On the opposite side of your newly cut wires, add butt connectors. These are crimped secure the same way as the other connectors. Halfway crimp the other side of the butt connectors, to make them tight enough to stay on the stereo pins, but not too tight.

13. Almost done! Run the aux cable to where it will finally reside. I ran mine underneath the center console and into the console box. I drilled a hole in the back and ran the cable through there. To do so I removed the cup holder and drilled.

14. Add butt connectors to the end of the two ground (black) wires. One from the XM connector, and the other from the bare wires in your AUX cable. NOTE: I believe you can also splice these two wires together and just have one connector to the stereo. I just chose to go the other route.

15. Connect the wires to the XM pins on the stereo. Two wires (left and right) will come from the switch and your 2 ground wires. Match the left and right to the left and right from the XM connector. Add the ground from your xm next to this connection, and add your ground from your aux to the pin below your other ground. See picture below for illustration. http://imgur.com/CeUTI.jpg

16. Test your connections!!! Connect your device. The way this works now, you will listen to both your AUX and XM from the XM band on your stereo. Hit band til it goes to XM. When the switch is in one position, you will hear your XM station. In the other position, you will now hear your Iphone or whatever you are listening to. Might as well test your FM and AM while your at it, or you could spend another hour ripping apart your dash to plug your antenna in :p

If that works, you are all done! Put your dash back together and enjoy!

Obviously there's more than one way to skin a cat. You could use the factory harness and splice into those wires if you're just using the aux and not XM. You could add the switch to ground and not the L/R. This is just how I connected my stereo. Good luck. Let me know if you have questions.

Great writeup bro! You should clean it up a bit and post it in a new thread so people can find it easier.
I do have a couple questions, though. I just put a sub in my car, and I ended up purchasing a new wiring harness which included the satellite harness (my car does not have xm). The harness has 5 wires, and the manual shows the pinout as follows:
White - Right Audio Signal (+)
Red - Left Audio Signal (-)
Black - Audio Common
Green Black - "Cel Tel Voice Low Ref./Navi Audio Signal (-)
Green White - "Cel Tel Voice Signal/Navi Signal (+)

Can you tell me which colors you spliced for L/R? Going solely by the pinout, I would have gone with red/white/black but obviously you already figured it out.

Thanks man! The factory harness doesn't have the same colors, but based on what you described, yes, I would go for the red white and black. If you are completely cutting the existing wires and splicing the aux wires into the harness, then this should be all you need.

Just a note though, if you are tapping your wires into the existing wires AND you currently can hear XM audio (preview channel or any other channel) you're going to need to either completely cut the ground cable, not tap it in. In my experience, the XM audio signal interfered with the aux signal (even if the XM was on the RADIO ID station, which doesn't broadcast any audio). My guess was this was due to the song information being transferred to the radio.




FYI - the green cables work with car handsfree bluetooth systems or On Star, where it cuts the music and plays whatever is coming over there when they receive a signal. I thought that would be great for an aux, unfortunately, they appear to be mono only, and you cannot control the audio volume from your device with the HU when using this connection. When it receives a signal the HU displays "phone" or some sort.

I was able to do that on one of my previous cars but that one had xm and this one doesn't. I don't have the monsoon system either. So would getting a new head unit be best? I want to get a pioneer in dash with the LCD screen and the aux out.

Ok so I took out my cd player and tried to get aux using the method posted by torridpsu and I had no luck. I think that my xm is not working. How do you put the stereo in xm mode? I have the monsoon from a 06 gt and it has the p-type button on it. If I have to go to a dealer to get it activated will I get charged for this?

yup...but price varies so call around. Tell them you need a stereo relearn.
I paid $80 to get mine reprogrammed & found out later that another dealership only charges $40. DOH!!!

There is an easy way to know whether your car stereo is activated for XM. Hit the band button on your stereo. If it goes to the XM Preview station after your AM station, then your stereo is set for this mod. Otherwise, it's what Lampoon said.

That's what I was afraid of, guess I will start calling around tomorrow to find out prices. always spending money dangit.

I went to the dealership and the guy told me that my cd player wasn't xm capable... :mad: Here is a pic of it and maybe someone can confirm if it is or isn't. When I push the band button it only goes between am fm fm2, no xm preview but the back of the cd player has a spot for a connector that torridpsu says is for the xm harness.

It would need the XM module and it would need to be reprogrammed.
Looks to me to be the one that works.

That guy was so totally on drugs... and not the good kind, either! :crazy: Your radio is indeed XM ready, and if you wanted to add the uPAC or similar adapter, it will work fine.

@Nackles. I'm assuming you're not interested in the XM, just the AUX IN? Well, as others have said, that is the correct stereo for XM, but if the spot in the back had no cables in it already, then you may not have the XM adapter in your car? If this is the case, I'm not sure that you will be able to convince a dealership to unlock your stereo?

I don't know this for a fact, but I could imagine a dealership telling you that they can't unlock the stereo without the XM module (and this may be true, but I doubt it, esp because I believe that port also works for a CD changer too).

Personally I would try a few more dealerships if it were me.

No I don't care about the actual XM radio and no it doesn't have the module in it. I guess what it amounts to is that I have no cheap options. I hate those fm modulator things. Is that metra thing the only alternative when using an aftermarket stereo?

Yo G6 owners! Great site, great info!

Just wanted to add a few details of my aux input adventure in my '07 GT convertible. The car has the 6 CD radio and XM that goes to preview when I select it from the band button (actually XM1 & XM2). I have no intention of using Sirius or XM so using Pandora, or something similar on my EVO will fit my needs.

The work that torridpsu did applies to any headphone output device so I decided to go that route. I didn't actually want to hack the original harness so I bought a PGHGM3 harness from sonicelectonix.com (http://www.sonicelectronix.com/item_16887_Peripheral-PGHGM3.html) for about $16 w/ shipping. Then a trip over to R'Shack, I picked up a 2 pack 1/8" panel jack for $3 (#274-249) and some heat shrink tubing for $6 (#278-1627).

The harness came in and I looked at what I needed to strip out of it. Essentially unwrap the whole thing and pull the wiring apart so you can follow them. The 12 pin plug & jack are all you need. I removed the 3 pins from the XM radio side of the harness and cut the other 3 wires at the adapter box end of the harness. All that is left is the unused brown wires and the 3 wires that go back to the radio side of the 12 pin jack.

(Unused parts on the left, good stuff on the right)

Next, to figure out which wire goes to which pin I did some searching and testing and found that on the PGHGM3 harness (from this vendor) the grey wire is the right channel, the white wire is the left channel, and the black w/white stripe is the ground. On the panel jack the tip is the left channel, the ring is the right channel and the sheild is the ground. As a note the factory color codes are green w/white for right, brown w/white for left, and the tan is the ground.

For reference I have these photos of the backside of the radio with and without the 12 pin connector.

Solder the wires to the jack (protect your console with a towel or something!) and use some shrink tubing to insulate the solder joints. Test your connections to the radio.

I mounted the jack in top panel of the console pocket. That way I can run the headphone cable out of there to my player or, if unplugged, it is unseen. I finished by taping the entire adapter harness.

I found the volume level is a bit low from the EVO to the radio. To adjust for this I run the EVO 1 click down from maximum and I set the EQ in the radio like a pre-amp, adjust the treb, mid, & bass up by 5 clicks each then adjust the sound preference from there. This gets the volume level close to the FM and CD.

Just wanted to give back, with help from this site I am enjoying my aux, enjoy yours!

:beer:

Great writeup Jon. Glad to see this method work for someone else!

Hey Jon, try one of these, or something like it!

Oh and torridpsu, could you tell me what parts from radioshack i would need to just install the aux input without XM?

I just did this on my girlfriends car. I used the updated unit though,(http://www.amazon.com/Scosche-FM-MOD02-Universal-Modulator-Satellite/dp/B001QBG614) and it works great. I installed the switch and input plug in the little cubby hole just like the original poster did.

However I ran the positive to the same place in the pictures which was the radio fuse not the A/C fuse. It is constantly hot so the FM Modulator has to be manually switched off every time the car is turned off. I could not find anything labeled A/C fuse on the fuse panel. The only places I could find to hook the +12V was to a constant hot or the HVAC fuse that was only hot when the ignition was in the "Run" position.

Is there a place I can hook it that will keep the unit powered whenever the radio is on? The radio has a feature where it will stay on after you turn the ignition off until you open the drivers door. I would like the FM Modulator to be the same way. Is that possible?

Try the heated seat/windshield wiper fuse. I put the power for my sirius radio there and it turns on with the radio and turns off when I open a door.

Thank you for this! It does indeed turn off when the door is opened just like the radio. This information should definitely be added to the guide in the first post.

Isimple IS77. Find it wherever..

Universal Antenna junction behind the change holder or whatever it is to the left of the steering column. Pull the left dash piece off and youll see it.

Pull both center console kick panels off- they just come off by pulling forward.

The iSimple IS77 comes with iPod cord to charge and play iPod or you can use aux for any mp3. You could use both- you just would need to use Y-adapters. You'll see we're I made my ground- next to the factory ground in the lower center console by the fuse box. To get power use a 7mm and take out the three screws holding in the fuse box and twist it around so you can see the wires goin into it- the where the two brown wires going into one hole- that's an ACC power.one goes to the ACC on ignition harness so that is the best bet and most reliable. Then you can put the cord wherever you want- I just put it in the cubby- and then mount the switch the overrides the radio station wherever you want. The switch over rides t 87.9 so you can have near Cd like quality playback.
