G6 owners rejoice! I found a cheap way to add a quality auxiliary input to a stock G6 headunit! I bought and installed a
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 (
). You will need to remove a good portion of the dash to get at the back of the radio, so [ame]http://www.g6performance.com/phpBB3/viewtopic.php?f=29&t=5991[/ame] 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.


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.






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 confirming the equipment setup in the first post worked in my 05 base model g6. (no monsoon) the only issue i have is it sounds like i'm in a cave. i adjusted the treble but its all the way up now it sounds close to perfection but you can still tell its off a bit if you listen closely. no static interference though, im guessing the hollow sound is interference of some kind, any help? other thaan that it works perfectly. only costed about 60 bucks with shipping and handling.
Thats cause you need to get it programmed.

the radio or the modulator? cd's and other radio signals sound normal.
how do i program it?
Tech2 is the only way and at a dealership. They will charge you from
FREE to $80 to do it.
I want to clear up some confusion with at least the iSimple GateWay ISGM573...

I have the 6 disc monsoon system in my 06' GT, BUT DO NOT HAVE XM. I didn't need anything unlocked or reprogrammed with a tech2 to get the kit to work. I have the "band" button and the extra 12 pin plug in on the back of the radio IF I had XM installed. All I needed to do was plug the kit in and with the kit plugged in, XM now appears when I hit "band" where as it never did before.

So, again, for this kit, you don't need active XM or have anything unlocked on your radio, you just need the monsoon radio with the "band" button above the volume knob.

I hope this helps.
I have a 2005 nearly stock G6 and would love just a simple RCA or 1/8 jack line in so I can plug in any kind of audio source. Sort of trying to avoid the modulation route too.

Just wanted to ask if i'm SOL if I have neither XM capable nor the Monsoon sound system. I'd rather not have to disassemble my entire dash to see what kind of ports my stock stereo has.

On your radio, do you have a "band" button above the knob for your volume? If you do, this mod should work. If you don't, then your SOL.
I've been wanting to do the same thing. I've cut and pasted three options I was just e-mailed from www.discountcarstereo.com:

There are at least 3 devices that can be used to play iPod devices on the 2007 G6 Radio:

To playback music via Bluetooth:
http://www.discountcarstereo.com/iSFM21.html
You will also need this antenna adapter:
http://www.discountcarstereo.com/BAA34.html

For audio playback from iPod, iPhones, MP3 players etc
http://www.discountcarstereo.com/iSGM533.html
Most customers purchase this part with the optional iSPDC11 dock cable which charges the iPod (no controls)
http://www.discountcarstereo.com/iSPDC11.html

The most complete adapter is available here:
This one will play/charge/control and display iPod text on the radio screen. It also has an auxiliary input for non-iPod devices with 3.5mm or RCA outputs (ex.Mp3 players, DVD players, etc) http://www.discountcarstereo.com/iSGM573.html There are other features to this product-- see link above for full description including user manual, installation manual.

Please note that the last two adapters work if the radio is Satellite radio ready -- you may not have an xm tuner, but the radio must support this factory option otherwise you will need to have the radio programmed by a GM dealer.
Compatible radios must have a "BAND" or "XM" button on the face. (most are already programmed but there is no way to tell especially if you don't have the Tuner installed).

Hope this helps - I'm headed for the 1st option, so that I can stream music from Pandora and Slacker off my Droid, and I don't have to connect an extra cord.

adding a bluetooth option....

Yep, the next step.

Continuing the low cost theme, bought this adapter from Amazon.

Belkin F8Z492TTP Bluetooth Music Receiver


Good specs, good price, so I added it to my previous aux mod, allowing me to plug in any MP3 player or bluetooth attach any smart device.

Plays Pandora or MP3s straight off my phone without any wires. (Well OK, have to plug in the phone's power cable after a few hours of listening)

Installed a widget app on the phone that turns on the bluetooth and connects to the Belkin by pressing one icon.

Did have one issue where I have a dedicated power converter (hacked car USB power adapter) that made a static noise. Seems that these converters use a switch mode power converter chip that is great for charging but makes noise on the audio side. Tried several before I just gutted one and used a 7805 from R*Shack as a 5 volt supply. The Belkin only takes about 180mA, so with the voltage drop and current output it dissipates less than 2 watts, not much heat at all.

After everything I have about $30 in the mod, it is dead simple to use and sounds great to boot.

Much discussion about bluetooth compressing the audio, etc, etc. Well with the A2DP and EDR the bluetooth side isn't going to affect the music quality at all. Pandora (free version) at best is 192K and most compress MP3s to 256K or less, so unless you are listening to a CD/DVD you are losing some audio quality.

I am quite happy with the results, YMMV.

Subd for future reference. Awesome write ups guys!! My girl will be very happy once I do this for her bc she is very displeased with not having an aux jack stock like her past 2 vehicles lol

I used that same unit. It works great, but with the G6 power always on, I have issues with having to unplug it and plug it in in the center console to get my phone to connect. Not an issue for me, but could be for you where that unit is located.

And regarding the noise, I added a ground loop cable in between the bluetooth and the connection to the stereo, and that solved that problem. Something like this.

bluetooth power....

@torridpsu

Found a wire that is powered the same as the radio and did a vampire tap.

Ran that to my hacked converter and it works great.

No problems with multiple phones using the bluetooth.

As an added bonus it has spousal approval so I am good to go. :D

OK, I added a custom aux input on the xm connector and the band button does not change the radio to xm mode to access the aux input. I talked to the dealer and they don't know what "programming" means. They say that they can "update" the radio software for $100. "Updating" does not sound like "programming" though. I spoke to "Specmo" technical hotline number they gave me and they said that if there is an input on the xm connector then the band button should work without any "programming" and actually they didn't seem to know what "programming" was either. Can anyone tell me which one has their head up their a$$?
Okay, I've read through this thread and I'm 90% sure I'm about to select what I need, but I want some clarity to make sure.

I have a 2006 GT with the 6-CD Monsoon system and the SRC button. XM is NOT activated (I can't select XM to even get Radio ID.) If I'm understanding everyone correctly, I can order this part:
http://www.pac-audio.com/productDetails.aspx?ProductId=1080&CategoryID=45

And once installed, I'll have to take my car to a dealer for some type of programming to enable the XM slot, which that harness attaches to on the back of the radio, which will allow me to select XM and get output from the 3.5mm jack, correct?

I'm seeing a lot of info in this thread about harnesses, radio confusion, FM modulation, direct wiring, etc., and this kit looks like the easiest method to get some kind of Aux input, which is all I care about. So will this harness work for me?
I have a 2006 GT with Monsoon and XM is not activated. There is not even an XM receiver plugged into the back of the radio. The dealer doesn't know what I'm talking about when I mention the programming. If that harness works for you I will buy one too. Please keep us posted.
If your post is in regards to mine, I'm actually asking the question. I don't want to go through the hassle of slapping $100 on a harness that doesn't work. :(
Akucaen, I was responding to you. I understand where you're coming from since I'm in the same position. Hopefully, someone else who was in this position in the past will respond.
So my fiancé has an 07 base. No xm or anything like that so I went with the scosche wired fm modulator from the first post. Well there's a second version out now for the same price. And I just finished installing it. Took me about an hour from first screw loosened to last screw tightened lol and that was testing it in the middle to. And I am very satisfied. It works like a champ. A little bit of white noise at loud volume when music is paused. But when music is playing its perfectly clear. IMO 35 bucks well worth it. :beer:

Will the factory radio still work once you install this kit?
