I've had an RP4-GM11 for a couple of years now,no problem at all. So good, I got a second one for the TB. Helluva lot better than the several failed Metra crap I went through.
Hey guys I can't seem to get my new rp5-gm11 to work correctly. So far no steering wheel controls and no audio from onstar. The head unit shuts off when I hit the onstar button but no onstar voice. It's driving me nuts that I can't get it to work right.I have it paired with my sony xav 602 BT, my factory bose amp has been removed.

I have the same kit running in my Envoy and it works without issue. However, I think I may know what your problem is. If I recall correctly, I believe its been mentioned somewhere on the forum that the On-Star is powered through the Bose amp. I can't remember what thread it was, but when I was looking into replacing my failing Bose amp in my old TrailBlazer with an aftermarket one, there was a trade off between losing On-Star in order to retain working speakers in the doors/dash. As far as the steering wheel controls go, do you have everything wired correctly? those should at least be working excluding the On-Star.
There is a good chance I'm wrong though, I think it still works if the amp is bypassed but I'm not too familiar with wiring/electrical systems in these trucks.
