Can someone tell me what harness I need to keep all the functions of the new truck (2007 Chevy Silverado Classic with Bose and Onstar)? I am thinking GMOS-04, but others are telling me something different. Someone also stated with the Scosche adapter I need another set of speakers for Onstar? They said I could use Scosche DCGM09 if I do not care about losing Onstar. I don't really care what it costs I just want to get the right one. Would everything except Onstar work with the DCGM09? Would the GMOS-04 be better? Thanks everyone!
