Thanks for the heads up about the grounding. If I have any more problems I'll definetly try that.
There is nothing wrong with the factory HU, IMO, but its really my wife's car. She LOVES her satellite radio. We already had the aftermarket HU in a saturn that got totalled (some ppl need to learn red light means STOP! - not my wife...) and I tried to put it into the GP.
I know what you mean about its getting harder to replace stereos in cars, which is disappointing. I generally don't like the look of factory stereos, especially those big oval things with a million buttons and knobs. However, I have an 09 G5 and I love that stereo. No need to replace that one.
