silverado nav install
Mine came with the single disk CD/DVD/MP3, bought HU#25797978 off ebay, installed antenna and HU. Have found several threads talking about install, plus the vss connector and tieing into the onstar, which I haven't done yet, (did find it on ebay and purchased). Did you have any major problems at the dealer?
