Suspect its age will not allow for updates. I get an email from TomTom every other month telling me my older device is too small for Euro maps and I need to purchase a new device for circa £300. Gits have also disabled journey ETA's etc to encourage a sale. Determined to keep it for UK maps just to spite them!
I know its a ploy for you to buy a new satnav from them but I will just use google maps free on my phone rather than pay out again !! I just thought there could be a way of utilising this tomtom but with some other maps installed someone out there must of done it
