My daughter's Tomtom Start has gone on the blink after a software update. It now no longer finds any satellites (and yes, it has been left for over an hour outside).

We've tried a soft reset via the on screen menu and also a hard reset via the hidden reset button. We've tried re-installing the software updates but that hasn't worked either. There doesn't seem to be any way of "rolling back" the software as my daughter has never done any back-ups in the past.

We've getting to the stage of returning it to Tomtom but I wonder if anyone knows any other ways of restoring its functionality? It just seems odd that it was working fine until the software update and then stopped working. I feel there ought to be some easy way of sorting this out.
