Only if you install a GM battery with side terminals. Actually, I have them in my Jeeps and I have no idea on how to recalibrate them. I think you press a button and then drive around in a circle! Odd, but true. According to Dodge (on my Ram '11 hemi)... Compass calibration This compass is self calibrating which eliminates the need to manually set the compass. When the vehicle is new, the compass may appear erratic and the CAL symbol will be displayed. Complete three 360 degree turns in an area free from large metal or metallic objects in not less than 48 seconds. The CAL symbol will turn off and the compass will function normally. Manual compass calibration If the compass appears erratic and the CAL symbol does not appear, you must manually put the compass into the Calibration Mode. To put into a calibration mode: turn on the ignition and set the display to comp/temp. While pressing the US/metric button, press the comp/temp button for at least 10 seconds until the cal symbol appears. Release both buttons and complete three 360 degree turns in an area free from large metal objects in not less than 48 seconds. The cal symbol will turn off and the compass will function normally. Ok, I know the 3 circle tricky, two of my Grand Cherokees are like that, the third one has the indash nav and I think it uses the mag compass & odometer as sensors to dead recon when in parking structures and tunnels as the map still updates without a GPS signal. Better cal it out with some parking lot donuts Lol there's some amazing info on here I get a feeling I'm gonna be learning a lot from this forum, thank god for the search feature hehe

Ahh just what I was after, thanks. Ready to get started!
