What does the Service Menu show you?
I would guess that your GPS antenna or receiver is defect. But you can confirm this in the service menu
You should check 4 key items:
GPS signal
What S/N values do you get and what is your GPS status?
You want a 4D fix. Of course, you must be outside...
Dead Reckoning Signals
Does your Gyro value properly centre on 2500 +/-100 and go up when turning right, down when left, and back to 2500 when straight ahead?
Does your wheel sensor show 0 when standing still, a positive value relative to speed going forward, and a negative value going backwards?
Does your direction show forwards in all gears other than reverse, and Backwards in reverse gear?
My guess is that Dead Reckoning is fine but GPS signal is faulty.
PS: compass calibration is performed automatically at every power-off and vehicle shutdown.
