How hard is it to hook XM and Onstar back into an aftermarket HU?

 

You can retain onstar by installing the gmos-lan-04 depending on what year of car you have. This is used for 07+ with onstar and pioneer 7 speaker. I just recently did mine and it was easy. Just read the directions. Also you will notice your chimes are alot louder as well as your blinkers.

 

I have an 08.... and I'm about to get an aftermarket HU and I want to make sure I don't lose onstar, xm or my steering wheel mounted controls.

 

You will lose XM as well as your steering wheel controls. There's a module out there that retains your steering wheel controls, I believe it's in the FAQ. Also there's a pretty good writeup on how to use your xm antenna.

Quick question: Do you have the 08 with pioneer 7 speaker? If not I believe you use the gmos-lan-03 (Correct me if I'm wrong please.)

 

yeah I have the 08 with the pioneer speakers and 10" sub

 

I thinik the 08's are the same as the 07's in which case you would need a GMOS LAN 04 to retain On Star. The steering wheel controls can be used by adding an adapter made be PAC, the exact part # is in the FAQ at the top of the section.
As for XM I think you have to buy the recievr to go woth the HU your looking to put in, I may be wrong but I don't think theres much of a way to get around it unless you can adapt the stock reciever to work with aftermarket, its in the rear deck lid.

 

****....this is gonna be a bitch of a task to keep everything working

 

xm will require you to get an xm module for ur aftermarket amp. Not sure if ud have to purchase a subscription or not but thats up to xm... also expect some changes with the recent buyout/merger with sirius

 

hmmm, im wondering if i should go through all this trouble or just get a clean sweep and run my sub through it. Seems like a **** load of work and adapters I would have to buy to keep everything working, and even then I have to make sure it all works.

XM/Sirius are not worth it anyway, there a pain in the ass, 200 channels of talk freaking radio, waste of money.
For the money your going to spend on a Clean Sweep, might as well get a whole new HU. I suggest something with a USB hook up, the sound quality is much better than CD, and its so much easier just putting music on a jump drive than it is burning CD's. I have one of those huge CD' cases, it sits in my office at home. Now I just have a hand full of jump drives that all sit neatly in the rear cup holders rather than taking up the whole back seat

 

Alrighty, I decided that I'm not gonna worry about xm, i will never use it that much anyway. I found the harness I would have to use for the OnStar. I was looking at the harnesses for the steering wheel mounted controls, but there is a bunch of different ones and I'm not sure which one would work on the cobalt. I searched around but I couldnt find any specific part numbers for any of them. Anyone know which exact one I will need? I have an 08 with the 7 speaker pioneer btw.

 

depends on the HU

 

oh i see, well im most likely going to be getting a pioneer. I had one in the past and i liked it and i figure i might as well stick with pioneer.

Thank you, you are the man.

I was just looking at decks and I really like the AVIC-F900BT but it isn't listed for the SWI-PS Interface you gave me a link for. Do you think it would still work for it, and they havent listed it because it's a newer model, or will it not work?

 

it should... only way to tell is if it has a lil remote 3mm type plug in the back of the unit. check online pics

98% of them will have it PAC doesnt always update their website

 

yeah that's what I figured. I'll check it out to make sure.
