The compass/temp display in my '08 FX2 is erratic. Sometimes when I start the truck, it displays "CAL", other times it displays normally. If I shut the engine off when "CAL" is displayed and turn it back on immediately, the compass and temp display as it should. If I drive in a circle three times, it will reset as well. I don't want to drive in a circle every other time I start the truck.

Any suggestions on how to fix this problem will be greatly appreciated.
