Hi,
just question - why last maps of EU are splitted to NORTH and SOUTH? Could it works with one file?
Personally I preffere just one file as I had some issue with multiple map files inside my Garmin (even if I had "ON" only one map in maps settings).
Sometime it created fatal troubles in navigation.
Solution I only found was rename file extension to some non-map extension name. (or delete other map files)
