Module, Compass: Description
The Compass Module is an integrated part of the Combined Rear View Mirror Module (CRVMM). Refer to MODULE, COMBINED REAR VIEW MIRROR (CRVMM), DESCRIPTION .
The following explains how to calibrate the compass:
| Setting Name | Selectable Options | ||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Compass Variance | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 |
|
NOTE:
When the "Compass Variance" feature is selected, it allows the compass variance to be set to any number from 1 to 15 per the compass variance zone map figure. Compass Variance is the difference between Magnetic North and Geographic North. To compensate for the differences, the variance should be set for the zone where the vehicle is being driven, illustrated in the zone map. Once properly set, the compass will automatically compensate for the differences when calibrated, and provide the most accurate compass headings. |

Press "Compass Calibration" on the touchscreen to enter calibration. To start calibration of the compass, press the "Yes" button on the touchscreen and complete one or more 360-degree turns (in an area free from large metal or metallic objects). A message will appear on the touchscreen when the compass has been successfully calibrated. Keep magnetic materials away from the rear view mirror, such as Mobile Phones, Laptops and Radar Detectors. This is where the compass module is located, and it can cause interference with the compass sensor, and it may give false readings.
