The current direction, in which the vehicle is pointing, appears in the compass display. Eight different directions and up to two letters (N = north, NW = northwest) can be displayed.
Familiarity with the function and operation of the compass system is needed if there are customer concerns.

Use the Vehicle Diagnostic Tester for repair work or Fault Finding.
Check all vehicle equipment (clock, convenience systems, etc.) after connecting the battery. Refer to BATTERY and/or the appropriate service/repair/system information.
Using an antenna that is attached to the rear lid by magnets or any remaining magnetization could cause the compass module to not work correctly. For complaints of inaccurate or faulty direction displays on the compass module, ask the customer whether a magnetically adhered antenna is being used before starting repair work.
