I am lost.

My electronic compass in my JK always says S or SW. Anyone have this problem? Do I need to just get a new one or is there some way to fix it?

Is anything sitting on top of the center of the dash, above the radio?

he means do you have an upper tray, and if so, do you keep your phone in it.

Easiest thing to try first if you cant already, disconnect your battery for a few mins.

Then there is some setup procedure for the compass i think i have read somewhere..

Heh Heh, mine is always off, I've got the Rockhard crossbar in front of the sensor

Just start looking for some moss on the side of trees, you'll be OK

Don't forget to watch the Geese flying-V-faces South

owners manual is your friend:

Manual Compass Calibration
NOTE: Before attempting a manual compass calibration,
the engine must be running and the transmission
in the P (Park) position (if equipped).
Compass calibration can also be requested. To manually
calibrate the compass, you must first enter the variance
mode. Press the and hold the left button (located on the
instrument cluster) for approximately 10 seconds to enter
the variance mode, and release the button when the VAR
(Compass Variance) symbol appears. The current variance
value will also be displayed. Once in the variance
mode, it is necessary to release the button, and then press
and hold it again (approximately 10 seconds) until CAL is
displayed (solid not blinking). Manual compass calibration
has been initiated. Drive the vehicle slowly in one or
more circles under 5 mph (8 km/h) in an area free from
large metal objects until the CAL symbol is extinguished.
When the CAL symbol no longer is displayed, the
compass is calibrated and should display correct headings.
Verify proper calibration by checking North (N),
South (S), East (E), andWest (W). If the compass does not
appear accurate, repeat the calibration procedure in another
area.
Compass Variance (VAR)
Variance is the difference between magnetic North and
geographic North. For proper compass function, the
correct variance zone must be set.
Setting the Compass Variance
Refer to the variance map for the correct compass variance
zone. To check the variance zone, the ignition must
be on. Press and hold the left button (located on the
instrument cluster) for approximately 10 seconds to enter
the variance mode and release the button when the VAR
symbol appears. The current variance value will also be
displayed. To change the zone, press the left button once
to increment the zone. The default is Zone 8. After Zone
15, the values will wrap around to Zone 1. When the
correct zone is displayed (per the Compass Variance
Zone Map **look in your owners manual for the actual map)
for the zone that the vehicle is located in, wait
for about 5 seconds, then the trip computer will store the
variance value in memory and the compass will resume
normal operation.
NOTE: The US/Metric display will change from English
to Metric or Metric to English before the VAR
symbol appears, however, it will revert back to its
original setting after programming the compass functions.

Thanks Nrock. Never thought you would need to calibrate the compass.

I only drive South now so my compass will always appear to be working correctly.
