bluetooth available instead of onstar
Guy's hello, I just came over to tell all gm guy's who don't like onstar but need blue tooth find Chris at http://www.costartech.com/
to buy his bluestar. You just unplug the onstar and plug his setup in and all the onstar buttons on the mirror then control your cell phone. He is local to me, so he delivered it and installed it last night in my 2006 gmc envoy denali. He told me he is an electronic engineer and got pissed when onstar change the setup, so it no longer worked in his 2001 caddy so he designed and built this unit for personal use. He doesn't have the one perfected for the 08's yet. Im posting this to help other people who like me hate onstar, I never met chris before last night.
