Hi, guys. First time posting here. I'm trying to do this same procedure. Not sure if it's been too long since they were posted, but the links to the PDFs aren't working. Any chance you can re-post them or see have other links? You help would be greatly appreciated as I found out the hard way also that the rear control is needed to have rear sound. >.<

The poster is no longer on this site and the attachments are long gone. If you are just looking for the wiring diagrams, they are available in the GM Techline eSI(see the links in my signature).

sytecyer, any luck with the bypass? I'm in the same boat (well, van :rofl: ), and need more than a wiring diagram to figure out how to make it work.

astrowill, that is a treasure trove of info you've assembled there.

I only just saw AstroWill's reply, thanks to your reply, and so haven't gotten anywhere yet. I'll try to get it done using the diagrams but not 100% sure I'll be able to, either.

If you need it ,I have the factory diagram that has premium radio and rear speakers without the rear controls

I would like both if you still have them handy. I don't see any attachments on this thread.

Wow. I never got this done and forgot I posted here. Did you have any luck with yours?

Thanks, it all started as just a place to hold some links.
