The GPS only takes you to the Middle of the conversion to Magnetic compass. It only applys the variation to True and not deviation. You have to apply the deviation from your Deviation card and finish the process of converting from True to Boat compass.
You did have your compass swung and now have a Deviation card for your Boat??

Note: this is when the GPS is set on Magnetic and not True. And the GPS will give you the variation of the area that you are in also.
