Hello,
Im new the the forum so please help me out. I have read a few posts and tried to search my problem and noticed some repeat names in the Nav threads so please help me out guys. I have a 2007 Silverado 1500 CC LTZ with Bose but it only has the 6 disc player. I found a refurb Navigation/DVD player online that was updated and tested at Gm P/N 15882766 they also sent me tha antenna. I took the radio and my truck to the local GM Dealership and they called a place from Gm called Part tech and they said my radio is not compatible with my truck. The person I bought it from said it works for tahoes, Suburbans, denalis, avalanches, and silverados. Do I tell the dealer to install it or does anybody know what part numer this radio is. My truck Vin is 2GCEK133X7157653 if it is helpful.

 

I honestly can not help but it sounds like if the dealer says it will not work it will not. The head unit for the bose and non bose models are completely different in that one sends out low freq. and has different harnesses than the one with bose.
