When I start the GPS like it is, My screen only shows a portion of it. When I change the rawdisplay to 800 and 480, it crashes.
I tried using highres=0 and it doesnt help. But if I try highres=1 then it has a huge display and it barely fits on my 5" gps screen.
I asked a similar question last week about the same or similar problem, but its a different GPS and the problem is a little different
