Hello, Please help. I do not see any solid information on how the Avic N5 By-pass should work. I moved yellow/black mute wire to open slot in-between both black wires on RCA harness and ground the parking brake wire to this wire. I also added a new good ground. When I go into system settings it shows my parking brake is on at all times. But I'm not able to use the search for address feature and many others. I was able to the first day I did the by-pass because I was able to put in my home address and work, but now if I want to go anywhere else I can not. I'm thinking about hooking up a switch, to manual turn parking brake on/off. Any suggestions or input from some-one with Avic N-5 would be greatly appreciated.
