Hi, I have a Garmin Nuvi 355.
I can't seem to understand what is the problem.
When i switched on the unit, it works fine till the main page when i select 'view Maps'. than it just hangs no matter how long i wait.
however, when i remove the SD card which contains the map, the unit works fine except since there is no maps, its blank and shows a qn mark?
Can someone please ...
