I just bought a 2007 Denali and the radio volume cuts off for 1 second every 25 seconds. (25 seconds of music, 1 second of silence, repeat)
the power stays on to the deck and everything is factory. Are there any other systems that are wired thru the Bose amp? (chimes, on Star, etc.) I'd rather go aftermarket but I want to retain all of my factory features. I currently have the flip down screen for the rear seats with the dvd slot in the head unit. What solutions have y'all come up with?

Does it matter what the audio source is (CD/Aux/MP3/FM/AM/Satellite/etc.) ?

If you turn on your turn signal, do you still hear it clicking at the same time as the music audio cuts out?

It doesn't matter what the source is. Every 25 seconds all sound cuts out for 1 second

If you turn on your turn signal, do you still hear it clicking at the same time as the music audio cuts out?

I can still hear the turn signal

I've seen a bunch of reports that this behavior is often related to heat. I wonder if it does it as much if you keep the interior of the vehicle a lot cooler than usual.
