Thread: 04 CompG new head unit questions

First off I'm kind of an idiot when it comes to audio stuff. I've done a few installs in the past tho. I have an 04 CompG, it's got the monsoon and onstar. I do not have XM so I cannot splice in an aux jack. That is the main thing that I really want. I want to be able to hook up my iPhone for music etc. I do not have a use at all for onstar, but I would like to keep my steering wheel controls, and if possible the radio info on the hud. But that's not a deal killer. I know I'll need a head unit, I've heard good stuff about the pioneer, what adapters will I need? Any pointers? Thanks guys!

GMOS-04 is the module you need to retain using the Monsson amp and retaining chimes and onstar.

Get a steering wheel control module for whatever HU you decide to get.

Bug fan of pioneers myself

My Comp G doesn't have XM either, but the previous owner installed a part by the name of "aai-gm24", and mounted in aux input on the dash next to the head unit. I push band until the screen actually says XM, and it works. I have the stock 6-disc monsoon.

I'll have to give that a try. It says I may have to go to a dealer and have the unused xm port in my radio activated which is do able. Thanks for all the advice guys!
