werock49 Posted March 20, 2017 Report Share Posted March 20, 2017 I have a 2008 Mazda cx 7 with Bose system. Does anyone know which wiring harness would work with my built in Bose system and my 6200NEX? Not all functions work with the one the installer used. Quote Link to post Share on other sites
jegonzo3 Posted March 22, 2017 Report Share Posted March 22, 2017 You can always go to Crutchfield to see what they recommend, but you don't have to buy there. Quote Link to post Share on other sites

gggplaya Posted March 29, 2017 Report Share Posted March 29, 2017 What functions don't work?? Most likely the installer is required to connect it so the parking brake disables certain functions when you're moving. Do the functions work when you have the parking brake on?
