Chrysler Repair: Compass Display Chrsyler 300, compass variation, underground power lines

Question
Hi Kevin, On a '06 Chrysler 300 with EVIC, I'm trying to get the compass display and it halts at "calibrating compass"  Are you aware of any flowchart for the various configurations of the EVIC system, and is the EVIC software flashable?  I've heard of horror stories with that, that even some Chrysler dealers either don't know how, or just will not flash it.

Thanks

Answer
COMPASS CALIBRATION
CAUTION:  Do not place any external magnets, such as magnetic roof mount antennas, in the vicinity of the compass. Do not use magnetic tools when servicing the overhead console.  


The electronic compass unit features a self-calibrating design, which simplifies the calibration procedure. This feature automatically updates the compass calibration while the vehicle is being driven. This allows the compass unit to compensate for small changes in the residual magnetism that the vehicle may acquire during normal use. If the compass readings appear to be erratic or the Electronic Vehicle Information Center (EVIC) displays “CAL”, perform the following calibration procedure. Also, any time EVIC service replacement components are installed, they must be calibrated using this procedure. Do not attempt to calibrate the compass near large metal objects such as other vehicles, large buildings, or bridges; or, near overhead or underground power lines.

Calibrate the compass manually as follows:


 
1. Turn the ignition switch to the On position.
2. Depress and hold the C/T push button (3) for approximately two seconds.






COMPASS VARIATION ADJUSTMENT
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, the compass variance setting may need to be changed.

To set the compass variance:


 

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



 
2. Turn the ignition switch to the On position.
3. Depress and hold the C/T push button (3) for approximately two seconds.



 
4. Use the SCROLL buttons (3) until COMPASS VARIANCE is highlighted. The “COMPASS VARIANCE” message and the last variance zone number will be displayed.
5. Press and release the FUNCTION SELECT button (1) until the zone number for your geographic location appears in the display.



 
6. Depress and release the C/T push button (3) to exit.
7. Confirm that the correct directions are now indicated by the compass.
