have experienced an issue after having the Navman for 3 days. The device reports it has been attached/synced to too many computers, (5 is the max recommended) Only synced to 2. Navman Tech Support tried to resolve. V impressed with response times. However ended up replacing. Got same model despite initial issue. Impressed with features and mapping. Not so impessed with the Lonely Planets Guide though which I've just bought. Lacking in detail in some areas.
