Summary: Don't know how I managed with out this, but I have been lead up some dead ends! However I do still always carry a map as in the event of a road closure I find it faster to look at the map than wait for the sat nav to find a new route.
Summary: I purchased this product couple of days ago and must say i am really pleased with it. I am used to maps so at first i was a bit worried about putting my trust into machine to get me from a to b without me having a clue where i am going. I was really surprised to see how easy it is to use. Good points: easy to set up - search by post code, street, city etc..
