Thanks for replying. My radio is the original Bose audio no Nav. I am trying to find the ground wire.I have a 2009 Envoy SLT with the bose audio. Problem the radio lights up but no sound for about 30 minutes into my drive then all of a sudden it comes on and sounds normal. I also noticed my door and headlight chime does not work. Any help would be appreciated.
Welcome to GMT Nation!
I'm having a similar problem right now. Are you using the stock radio/nav unit?
Mine will not play audio until the radio is on and I open one of the doors. The radio turns on and is functional, but no audio until I open a door. Try opening a door and see if that turns that sound on.
I'm still trying to track down the issue if it's a ground or wiring issue from the previous owner. My thought is that I have either a bad stock amp or someone installed an amp and it is wired incorrectly.
My radio is the original Bose that came in the Envoy. My sound does not come on when I start the car. It comes on about 30 minutes later as I am driving down the road. When it does it just comes on all of a sudden. I found an amp on Ebay. I going to try that. No DVD player.I think we do actually have the same wiring problem. We'll be working together on this one for sure!
So you also have an aftermarket radio that this happens with as well? Which brand/model interface and head unit are you using?
I'll look into the wiring to the chimes. I think that's what the issue is for both of us. When I open my door with the radio on. I only get sound AFTER I hear the door chime. It ends up being about 2 seconds after I open the door. So, I don't think it's necessarily a ground issue, but could still be a grounding issue.
Edit: Do you have the DVD player?
