overhead trip computer
Installed a trip computer on my 00 from and 02 but read that some calibration had to be done for direction and such. The manual states to drive the truck in several circles to accomplish this. Any advice on this?

First set the compass zone your are in:
Compass Calibration Zones
The zone setting is factory set to Zone 8. Check the Compass Calibration Zone map (below) to verify the correct compass zone setting for your geographic location.

- Gently press both buttons for three to four seconds until ZONE is displayed.
- Release the switches. Zone and the current zone setting will be displayed.
- Press either switch to cycle through all possible zone settings. Stop cycling when the correct zone setting for your location is displayed.
- Release the switch to exit the zone setting mode. After five seconds of no button activity, the module will store the current zone and leave the mode.
- For optimum calibration, turn off all non-essential electrical accessories (rear window defrost, heater/air conditioning, map lamps, wipers, etc.) and make sure all doors are shut.
- Drive to an open, level area away from large metallic objects or structures and high voltage lines.
- Press both buttons for six to eight seconds until CAL is displayed.
- Release both buttons and drive slowly in a circle until CAL disappears from the display (about two to three circles).
- The compass is now calibrated.
