Yea looks like you would have to send it to TomTom for repair but that could be quite pricy it might be worth looking at a new unit, Halfords currently do the TomTom 1 GB for £159.99 its a smart slim unit or you could go to another store if you dont like Halfords which alot of people dont! LOL Wherever you go though i would advise that you stay clear of navman, although you'll pick them up very cheap they are very unreliable!!
Hope this helps
