All,

When I try hooking up the parking cable at the parking park switch, both side were a negative signal.

Please help

one of them has to change. test them both again with the brake off and then with it on

All,

I've hook-up the VSS, reverse light and the parking brake according to the factory manual. On the system info. I've confirm the VSS signal and the is moving the sat signal is strong. The parking brake on-off fuction is now working. and the reverse signal (High and low). The arrow still is stuck on one location. I was able to modify current location on the screen, but the navigation never moves. I've confirmed that the demo mode works.

Please help.
