First off, I am a beginner, so sorry for sounding like a noob, and I appreciate all the help I get! :-) I just acquired a Pioneer AVH - P3200DVD. I want to install it in my 2005 Chevy Equinox LS which currently has the original factory radio. I will not be installing any additional equipment. I am under the understanding that door chimes and Onstar are controlled through the factory radio. If it will cost me less money, I can careless about keeping these features. If someone could help me select the least expensive yet appropriate wiring harness and mounting kit, your help would be greatly appreciated. I am currently looking at the Metra 70-2103 wiring harness and the Scosche GM1599B mounting kit, would these work, or am I way off base? Thanks!
