I live in Australia and have had my TomTom for about 7 or 8 years. Lost the Box, but the Serial No starts with ZE. Have just returned from a trip in which I was having connectivity problems and isolated the problem to a faulty lead. However when I got back onto my Drive Connect it has lost my Map off the device and now won't allow me to load a new one. The online Chat support doesn't recognise the Model No I enter, and there's no phone number to call. Can anyone help me please?
