Crutchfield has assured me that I will be able to use the harness they supply without any problems. Two different car installation places have assured me that I need a CAN BUS harness which doesn't exist yet for a 2007 Jeep Patriot. The installation places told me that the crutchfield harness might work but I would have problems with my check engine light and other things if I don't use a CAN BUS harness.
Has anyone had an aftermarket radio installed yet?
After doing more research and reading more posts here I think I'll be keeping the standard radio for now. I'm still going to install my aftermarket speakers, amp, and sub, so hopefully there won't be any quality loss by keeping the standard head unit.
