Is it impossible to ask supprt at garmin about your issue, they have create it in some way. Else you have to ask them you bought the gps unit or the gps maps.

I have an other issue, lost sdcard (microsd) due to an accident and it will not anylonger turning on. It might be power cord cable or something else. but if all maps is lost what do I do if I get it up and running again without any maps?

The maps are quite expensive and my garmin unit has quite low screen resolution, garmin echomap plus 42cv.
