medmondson Posted August 11, 2011 Author Report Share Posted August 11, 2011 That is fantastic. Despite some trepidation (because of many lukewarm reviews) I am looking forward to getting this beast into my dash. Quote Link to post Share on other sites
medmondson Posted August 11, 2011 Author Report Share Posted August 11, 2011 So I just had a conversation with Best Buy and the guy told me I need a $150 wiring harness because my vehicle is a post 2003 GM? He said it had to do with OnStar and system notifications? I couldn't give a shit about OnStar, is this thing really necessary? Quote Link to post Share on other sites

So you without that you wont have onstar or your dinger (like with lights on and doors open and stuff) and anything else that the vehicle might play out through the stereo.
