I'm heading almost due west and it says I'm gong North west. I'm fact I'm MUCH closer to going south west.

 

You live in the Yukon?

 

Have you tried setting the variance (holding down ((or in this case.. UP)) both the metric and comp/temp buttons for 10 seconds)? Then going through calibration?

 

Any magnetic compass will almost never read true "geographic" north. The field is distorted by your local geology. Each area has it's "declination", (like topo lines on a map). And it changes! Here it was 19- 1/2 *, (forget east or west), in 1980. IIRC now it's 16 something. It drifts, at least here! You can google that for your area.

Anyway I know nothing about a Jeep compass. Calibration, (as mentioned makes sense). I guess on boats they need to that. Metal and electric fields change the reading.

 

There is a procedure to recalibrate the compass in the owners manual. There is also a chart/map with a number to enter to identify where in the world you are to adjust the geodetic north variations.

Unfortunately I no longer have an owners manual to provide the details.
