My TomTom XXL failed the other day. Won't switch on. The power light does illuminate, though, when it's plugged in. Just before it failed totally, it kept on powering down on its own.
TomTom do a fixed price repair which is about the same as a new XXL from Halfords (89.99)- obviously now a run out model on special offer.
However, there are several independents offering a repair service for rather less - roughly 30 quid inc postage. Anyone used one?
