Hi all,

I have a .gma file within the Garmin Folder on my SD card. Does anyone know whats this file for and what exactly it relates too i.e the map image or the sd card id?

Also on the SD card is an .UNL file - im guessing this is the unlock code for the map?

I can open the UNL file - its just a bunch of regular numbers and letters, but the GMA file is a whole bunch of mess!

Thanks to all..
