i tried reset (10 sec power button), hard reset, created a small map for italy, put it on the navigator internale memory, deleted the old big eu map (3gb), rebuilt it via mapsource, and this morning it did it again.

fortunately, having the small map of italy, I disabled the full eu map, one reboot, and it worked. It also works 3d buildings, and the file is on the SD ...

sorry for spamming this thread, I guess now my problem is more related to the SD card / garbage on the navigator / wrong procedure in building the eu map from mapsource/ whatever else. which is the correct thread for this?

i will try it again in 10 minutes, while going back home.
