Twice now in the last 3 months my updates feature said that I needed to update Tom Tom Maps and its a huge update or 7gb or something. I stupidly did it last time before making a long journey. It then too repeated aborted attempts to update as it wiped the old map off and kept saying No Maps. I very stupidly agreed to update again, (using Wifi as Ive lost the USB cable). Its taken over 2 weeks of aborted attemnpts to update. It takes days to get to 47% then days to get another 2% then it says Internet lost and basically start over. What the hell is wrong with it? Any help greatfully received. I cant even see where I can buy a new Tom Tom USB cable for it?
