GPS and Compass show different headings

Hi all,

I know this is a beginner question, but here goes. On my new (to me) boat, the compass and GPS show fairly different headings. I have a Raymarine C-60 and a Richie compass. I would assume that the GPS is the correct heading and that the compass needs calibration, but how do I know for sure?

Thanks, Bill
