OK, I posted this somewhere else once. This solves the problem of parts (stock parts!) in the vicinity of the module that are magnetized, but it won't solve a big ol aftermarket speaker giving it false magnetic fields!
Take out the compass module. You have to use either a 13-inch diameter
television degaussing coil, or you can also use one of those bulk tape
erasers from Radio Shack. I think the television coils are stronger.
1. Hold the coil about 1 inch below where the compass module is and
rotate it slowly in a circular pattern. You need to degauss a 1-foot
area around the module location. Stay away from the speakers. I think
the unit must operate from a 110V AC source.
2. After 30-60 seconds, move slowly away from the rear compartment
while maintaining the circular motion. Move at least 5 feet away from
3. Close the trunk.
4. Do the same thing outside the vehicle, starting 1 inch above the
deck lid. Move at least 5 feet away and turn off the coil. I think
that these things can overheat and cut out fairly easily.
5. Put the module back in the trunk and recalibrate.
Hope this works. I don't know if the dealer has a degausser or not.
