Greg, I just got back from the lake to try out the new unit & was blown away at how sharp the down imaging was. Awesome! However, the Contour XD maps will not display. When I go to chart select, "auto" is displayed. I then attempt to click left or right and nothing happens, except for the normal sound. Unit stays in "auto". I've updated unit with most recent software:(5.50) and update was successful. Any ideas on a remedy? Thanks, Greg & thanks to everyone for the input.
