Pioneer AVIC Z1 Navigation not working

Recommended Posts

The aftermarket Pioneer Navigation isn't working.  Just recently bought 2001 911 Carrera (996).  I stop and set the parking brake as required but the navigation still remains locked and won't respond to any input on the touchscreen navigation mode.  It appears to me that the head unit (Pioneer AVIC Z1) thinks the parking brake is not engaged and therefore won't work.  Wondering if anyone might know the solution or what I might try to solve it.

When the parking brake is on, does the light on the gauge cluster come on?  It should.  Two things come to mind, the cluster bulb and the switch on  the parking brake not engaging properly.

I just looked at the installation section in the manual for the Pioneer and see no special connection for the brake sensor. I would recommend resetting the unit by pulling the fuse(s) for the head unit and amp. If you have the hifi system from factory that could mean 3 fuses. I could be mistaken, but I believe the Pioneer unit uses GPS data to recognize if the vehicle is in motion or parked. 


After resetting the fuses. Follow this procedure. See att. pic.

Also,  when parking brake is engaged the light in the cluster on the dash is lit indicating brake is engaged.
