Lowrance Elite 5 purple map

Hey. I have an Insight Genesis map on my Elite 5, and even though it shows contour lines, the map is almost all purple. How can i fix this? I already restored default settings, and downloaded the files again, but i keep getting this purple color in the map. How can i fix it?

And while we are at it, how do i change GPS units to degrees, minutes, seconds??

Or how do i change Google Maps units to Degree, minutes??
