Location problem - tomtom

[Ciaran]

I was using my tomtom unit on Saturday to get me from Stansted to Stranaer which is did fantastically well. I turned it off as I was at the boat and no longer needed it, now that I'm back in Belfast I've turned it on again and it still thinks I'm in Stranaer - it says waiting for GPS signal? Is there a way to reset it without loosing your saved preferences?

Thanks
Ciaran
