08 F250 Compass quit after install

[DBMaxwell]

I have an 08 F250 that I put in a Z2. The compass on the dash quit when I was done. My question is, does the compass depend on the factory radio, or did I screw something else up?

Have you tried calibrating the compass?

 

There are 2 wires that go from the compass sensing module in the rear view mirror to the instrument cluster. They are yellow/green stripe and blue/gray stripe.

---------------------

1. NOTE: For optimum calibration, drive to an open, level location away from large metallic objects or structures. Switch off all non-essential electrical accessories (heated rear window, heater, A/C, map lamps, wiper, etc.) and make sure all the doors are closed.

 

Start the vehicle.

 

2. Press the message center SETUP button until RESET FOR CALIBRATION is displayed.

 

3. NOTE: The message center displays CIRCLE SLOWLY TO CALIBRATE in the calibration function.

 

Press the RESET control button to start the compass calibration function.

 

4. NOTE: This step may require up to 5 circles to complete the calibration.

 

NOTE: If the RESET button is pressed during the calibration or 3 minutes has elapsed since the beginning of the calibration without driving the vehicle, the message center reverts back to normal operation and the INFO displays CAL until a successful calibration is carried out.

 

Slowly drive the vehicle in a circle less than 5 km/h (3 mph) until the CIRCLE SLOWLY TO CALIBRATE display changes to CALIBRATION COMPLETED.
