boy racer!

felt a bit of an idiot placing hambo on the nosecone of a McLaren's F1 driving simulator - but the blip must come before my self -image!
For the past 2 weeks every time we've turned on the mac, a pop-up appeared telling us to update the sat-nav. Yesterday i succumbed to this cyber bullying and updated the map of France.
Now i can't use it as the upgrade has 'mucked up' the map of the uk - so today's joyful task is to sort this out!
