I own a Nuvi 775T unit, with all maps installed on unit memory.
I want to use CityXplorer maps I have downloaded using this forum, but on a single SD card, not to change every time I am in a zone with relevant SD. One for al cities.
How should I copy the image maps (*.img) because all have the same name?
Each in a separate folder under Garmin base folder?
Or all image maps under one Garmin folder, but change each map image name?
What I have noticed that MAP ID for some cities are identical (ex. Helsinki, Madrid and Rome). How should my unit know for which maps are the unlock codes?
Any help apreciated.
