I wanted to share my experiences installing an auxiliary input on my Bose, OnStar, and XM equipped truck. I used a iSimple ISGM535, it is a completely plug a play system; nothing more then inserting it in between the radio and existing harness.
Unfortunately I did not get any pictures during the install process, but I have a few from after. The install was not complicated, but some steps were involved and it really helped having another set of hands.
1. I chocked off my tires and placed my shifter into first gear. Then I carefully removed the bezel surrounding the dash. The bezel just clips on, I started in the lower left and worked my way around.
2. After the bezel is off I was able to remove the radio. I choose to remove the climate control as well for more room and to not run the risk of scratching it. Pulling the radio was where the second hands come in handy, one person to hold the radio while the other person can wiggle behind it to disconnect the harness(s).
3. After everything was removed you simply clipped the supplied harness onto the existing one. Then find a place to hide all the excess wiring and the module. Then you can choose the location for your AUX port or cable. I put mine in the cubby just right of the climate control.
4. Reinstalling the radio was much simpler due to the extra length on the harness. The RCA antenna was still difficult, it was to short to pull out and connect. I had to fish around blind and feel it into the hole. To be honest, if I would have known how short it was I would have bought a 1 foot RCA extension and used that.
5. Now I reinstalled my climate control and replaced my bezel. I powered on my radio and pressed the band button until SAT appeared, then rotated the turner nob until AUX 1 appeared and press the second preset button the choose AUX1. (You will not have to do this every time, AUX 1 now appears as an option when I scroll through the band options.)
Notes:
Remove all the CD's prior to removing the radio. If you plan on working with the door open, I would disconnect your batteries otherwise you will have to listen to the chiming because the key is locked in when in first gear. When pulling the radio out, don't force it. Some of the harnesses have clasps and are really short. You will have to jam your hand back there and try and feel the harness off.
I choose to use a dual female 3.5mm keystone wall adapter so I would not have a cable hanging out, rather I would have a headphones port to plug in a aux cable. I attached a few images of it below.
The whole setup was just shy of $80.00, which is great in my opinion. I use my Android phone to stream Pandora or other services rather then paying for XM or burning CD's all the time.
I enjoyed the install and really enjoy the flexibility of my AUX input while still maintaining the stock look and functions.
If you have questions, I would be happy to answer them for you.
