exactly. both car batteries were on the drivers side of the vehicles, with the hhr on the right side, facing in

 

well, it turns out the radio was the culprit all the long. it was drawing power even with the acc turned to the off position. Replaced and everything is good to go

 

I have experienced a problem with my radio, a couple of times now when I have turned my car on, there is a very loud pop over the speakers, sounds like a short or a feedback problem. I thought that the first time it was because I was in the garage and it was the xm, but it has happened a couple of other times since then, out in the open. Any ideas what could be causing this? It only happens on start up and it is very sporadic.

 

Do you have the amplified premium system? It sounds like turn on thump to me but you would need an amplified system for that to occur.

 

I did get the stock premium set up.

 

I HAVE HAD THIS HAPPEN MANY TIMES, I.M TAKING MINE IN SOON TO BE LOOKED AT. DOES NOT SEEM NORMAL TO ME.

 

There are a couple of things you could do to take care of it but seeing as how it is the factory setup and under warranty I would let the dealership repair it rather than trying to fix it yourself.

 

Thank you!

 

Let me know what you find out, I would appreciate it.

 

I was gonna say why didnt he just pop the trunk and jump it straight from the battery in the back...but then I remembered that GM forgot to include the manual trunk release...this is why I have one of these
