I had my installer do the two wire ground and reset and I have the current updates from the cd. I was on my way home and everything was working fine and all of a sudden the improper connection of the parking brake came up again. I turned around and went back and he checked the parking brake ground and it was fine. He reset the unit and again everything was working until I got about halfway home and it did the exact same thing. I want to through my Z2 through the window and go back to my kenwood! I have a trailblazer and its a pain in the ass to get to the unit. Any thoughts?
