I have a 2007 LTZ with Nav, XM, and rear seat DVD. Whenever I put in a dvd and hit pause, or select XM and turn the volume all the way down, I can hear whatever is playing on the last FM station I had tuned in through the system as feedback.

It is very slight but it is there.

I checked out a couple of trucks like mine at the dealer and they did the same thing. Yukon, Avalanch, Silverado, Suburban. The common factor is the NAV unit and XM with rear DVD.

Anyone else having this feedback. It is best heard with the engine off and in a quiet setting.

Any suggestions? I have already emailed Chevy. Thanks.
