Compass Variance Adjustment - RHD

COMPASS VARIANCE ADJUSTMENT - RHD

CAUTION: Do not place any external magnets, such as magnetic roof mount antennas, in the vicinity of the Remote Compass Module (RCM) located above the headliner in the rear of the vehicle. Do not place any electronic devices (cell phones, laptop computers, Personal Digital Assistants (PDAs), portable DVD players, etc.) on or near the rear of the roof as the RCM performance may be affected. Do not use magnetic tools when servicing the RCM.





Compass variance, also known as magnetic declination, is the difference in angle between magnetic north and true geographic north. In some geographic locations, the difference between magnetic and geographic north is great enough to cause the compass to give false readings. If this problem occurs, or any time Electronic Vehicle Information Center (EVIC) service replacement components are installed, the compass variance must be set. The default for the compass variance from the factory is 8.

NOTE: If the vehicle is taken on long trips into a new variance zone the compass function may be effected. Compass variance will need to be updated to the new zone number to function properly.

EVIC EQUIPPED VEHICLES

Set compass variance as follows:

1. Using the Variance Settings Map, find your geographic location and note the zone number.





2. Turn the ignition switch to the ON/RUN position. Press and release the MENU push button (1) until "Personal Settings" is displayed.
3. Press the STEP push button (4) until "Compass Variance" is displayed.
4. Momentarily depress and release the RESET push button (3) to toggle through the zone numbers (1-15), until the zone number for your geographic location appears in the display.

NOTE: The default for the compass variance from the factory is 8. During programming, the Zone value will wrap around from Zone 15 to Zone 1.

5. Momentarily depress and release the C/T push button (2) to enter the displayed zone number into the compass unit memory.
6. Confirm that the correct directions are now indicated by the compass.

NON EVIC VEHICLES

Set compass variance as follows:

1. Using the Variance Settings map, find your geographic location and note the zone number.

2. Start the engine but leave the vehicle in "PARK".
3. Press and hold the COMPASS/TEMP push button for approximately 10 seconds until the "VAR" menu is displayed in the Compass Mini Trip Computer (CMTC) display (23).

NOTE: During programming, the Zone value will wrap around from Zone 15 to Zone 1.

NOTE: The US/Metric display will change from English to Metric or Metric to English before the "VAR" symbol appears, however, it will return back to the original US/Metric setting after programming the compass variance.

4. To change the zone, press and release the COMPASS/TEMP push button to increment the variance one step. Repeat as necessary until the desired variance is achieved. When the correct zone is displayed, wait approximately 15 seconds. The CMTC will store the new variance value in memory and the compass will resume normal operation.
5. Confirm that the correct directions are now indicated by the compass.
