I bought this device 2 weeks ago and use it for work as a delivery driver. From the outset it started to reboot itself after 20-30 routes. After another few days with tomtom support they said it was the battery and I could send it in for repair. As it was only a few weeks old I decided to replace it from the store I bought it and the new one also displayed the same "fault"! Tomtom are now claiming that it may be a corruption with my myDrive account!! I have now lost all faith in anyone within tomtom support actually knowing anything about their devices and as a last hope I have come to the community. Has anyone out there experienced this, know of a fix or know of any tomtom device that has traffic and actually works as described.
