My parents bought me this for Christmas as I kept stealing theirs - to a point that it lived permanently in my car! I really don't know how people survive without one - or how people managed before! The Dimensions are (WxDxH) 9.2 cm x 7.8 cm x 2.5 cm and its Weight is 148 g.

For those of you who havn't ever used one of these - they work by tapping in the postcode or place name of where you want to go and it brings up a map which you follow to your destination. It also has voice navigation so if your driving and can't look at it you will still know when you need to turn etc. You can set it to Shortest journey, Longest Journey, Quickest journey etc.. and if you need to cross a toll bridge it will come up asking if you want to avoid it - which can come in handy if you don't have any money on you - or a reminder before you set off to get some!

You can also put it in night mode so that in the evenings it doesnt shine so brightly in your eyes!

This is simply to use and a godsend! especially if your lost! If your thinking about getting one then I would definately say go for it!
