Before buying I was quite unsettled by the partially very bad reviews of the device. But since I do not quite good with Garmin was (C510 and Nüvi 1490T) I've ordered it to me anyway. The reason for the initial purchase was lifelong update. Bluetooth I do not need - I have to handsfree in the car audio system. I'm more than 60,000 KM per annum in sales force on the road and the Navi is a day with me in action. My conclusion after the first 5,000 KM: The unit navigates absolutely top (even in the forest on this KM-number I think is normal, it can always Navi users, no matter what device it uses to report). The update facility via the Internet is simple. For most here written by other bad reviews I wonder if the people the same device (or a device überhaubt) bought. If the Navi are lost or stolen, I would buy the same device again immediately.
