My 296 has just recently developed a bit of an issue. Basically the terrain map has gone a bit screwy. It seems as though the map over my home area has corrupted itself. When zoomed out, it's fine, but closer in, one 'tile' of the map just disappears, and the next one south has grown some extra hills, triggering the terrain warnings as I fly over them. The screen shots show this better. Spoke with Garmin Aust who passed me over to a Sydney agent, who directed me to the US website, but with no real help. I don't really want to fork out the US$150 for a new terrain map if it's not going to help though (considering the unit was bought new less than a year ago). Has anyone heard of this happening before?
