I bought before my vacation the unit. Installation and update were done easily and quickly. Although spoiled by Navigon, I found the routings not so bad. However, the device is once crashed in a tunnel passage. To revive it, I found no reset point. Had then the SD card is removed, after the device rebooted. Is so far does not happen again; maybe fixed by firmware update. However, the routing abroad Austria and Italy was not as precise. There was, for example. reported a destination in South Tyrol in Landeck, although in between were still quite a few branches. Until the designated branching point, the Nüvi has no longer reported. Only shortly before the target device took the routing again. Nevertheless, throughout not really gavierenden weaknesses. Have so far it 2 updates.
