WEF's 95

My 2007 Nav w/Bose now has a blank nav screen and no sound for anything. No request for a command, nothing from Onstar. If I push on the blank screen in positions I know should be active, I will see results in the HUD. If I move it to the "CD" position, it will even advance at the end of a song. That tells me it's working except for putting out the sound and display. Both fuses are good. I am ready to spring for a Kenwood DNX572BH but the local Chev dealer thinks it could possibly be the Bose amp. I don't know why that should affect the Nav display but I guess anything is possible. Any thoughts?? I've also tried the battery disconnect but no help.

Any warning chimes?

Sounds like radio is definitely bad either way.

No sound whatsoever. Best Buy has a sale on a Kenwood DNX572BH so I guess I'll take my chances.
