Unfortunately my wife's car has done exactly the same thing a couple of weeks ago.
Haven't got round to having a proper look at it yet, but my intention is to disconnect the battery for a few minutes and re-connect, then try it again. (make sure you have the radio's security code before you try this)
Other than that, I've no other ideas at the moment... just thought I'd have a look on the net!
