Title: Contour XD map Drifting along & no map on that part of bay
Post by: ron824us on April 20, 2011, 06:29:18 PM

I'm using the built in Contour XD map. 
Different parts of the map go to all to white & no contours, & no nav. aids.
Is there a way to reload the built-in Contour XD maps the unit came with?
