Jackal24,

Certain areas of Alaska exhibit the problem,
while others don't.


Complain to Lowrance support. It might help.


They said they couldn't replicate the problem and to return the unit. If
you have one, can you try zooming in to the airport 5NN and seeing if your
unit shows the problem. At a close zoom level on mine, you can see the
terrain disappears on part of the screen.

Thanks
