Compass recalibration???

Check owners manual, but basically there should be a set up menu, on the overhead panel then once you get to the calibration steps, then just drive around in a circle, a school or mall parking lot on a early wekkend morning might work. I believe that the secret is to get a full 360 circle in one motion. Also try to keep open area and not get too close to the buildings to avoid interference.

im not sure if you have to do anything with the menu, but find an open parking lot and drive in circles, you will probably need to get more than one full circle in (id say just drive in a giant circle for 5 min, if you hold the wheel steady you should be able to just keep the same loop indefinitely)

3 norths; grid north, true north, and magnetic north... grid north is map north.. true north is the actual north and magnetic north is where the compass will point.. you have to take in effect magnetic declination to get true north.. but you wont really need that unless your really looking for accuracy..
