EVO 2 Compass Heading Issue

This sounds like something is interfering with the EV-1 sensor, around the location. First, what is the deviation in the system? You can check this by pressing Menu, Set Up, Diagnostics, About Display, then scroll down to the bottom of the page where the Deviation is reported.

I would also make sure you are at the most recent software levels on all Evolution components, p70/R, EV-1 and ACU-200.
