Hi,

Thank for your answer "asprin624", but, basemap is not kb but mb....

version 6 isn' t 48kb, but 48mb
version 5 isn' t 49kb, but 49mb

On my garmin etrex 10 they have only 8mb in total memory

[Only registered and activated users can see links. ]

No expensible memory ( no micro sd card )

only possibility is reinstall original worldmap dem nr basemap.... is less than 8mb....

Thank you
