I know that compasses can lose their MOJO over time or the roof has become magnetized. Hopefully someday I can find an accurate replacement. I like having a compass.
Yeah. Mine was acting screwy too. That's why I pulled it. I thought it was the lack of mineral oil in the case.
There are magnetic adjusters you can tweak to realign, but if the whole instrument is way off, then you're out of luck.
I wish I'd bought a small [2-3/8''] general aviation magnetic compass instrument when they were affordable, but so what.

If you say it works outside the truck, then you might try a dash mount, rather than shielding it under the cab roof.
