got a question. I notice with my 997 that when I'm running the lake at max speed,which is about 27mph,that when Im zoomed in a bit that as I'm going the top part of my map gets lost. Like someone took an eraser and wiped the top part of the screen down about an inch or two. It does come back. My track lines do not disappear nor does the so called maps that are preloaded,but my hot maps do. My 797 never did that.If I zoom out it does not happen.Only if I'm zoomed in.
Is this just the refresh rate trying to keep up? Sort of annoying
