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.
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
! 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.
