grrr I got OH a tomtom for Christmas, he will use it all the time for work, especially when he's on call (which he is this week) It started playing up a bit, not turning on when not plugged in etc. Yesterday it stopped recognising the memory stick, then today it's saying no maps available. Its really annoying, OH has had about 8 calls since it started playing up, driving up to 30 miles for each one, and now he can't use it! I've googled loads to find out whats gone wrong, and tried loads of stuff but nothings working I got it from my brothers friend (it's brand new and from Argos though, but he gets them through his work) so it's complicated. My brother said he will get him to swap it no probs but how long will that take?! OH is on call now!!
