I am not quite sure if i am posting this in the correct forum, but here goes. My 2004 Chevy Tahoe Z71 has the factory Bose 6 disc CD Changer. I tried adding a cd tonight, and it whirred and whirred, it took the cd. Now I have disc 1-4 on the display with the cd indicator above disc 2, and it will not let me do anything, no play, no forward track, no display, no whirring. I tried turning it off, then on, changed it to the tuners, they work fine, but when i go back to the CD source, i get nothing but that display. I have seen other posts on fixya, but no one responded with an answer. any help is fully appreciated.
