ive often considered buying one but then i think about how often id actually use it and i recon i make a journey to somewhere difficult about once every few months and i can do without.
Until about nine months ago, I was a map man myself and couldn't understand why anyone would want a Sat Nav. Then, more as a toy, I bought a TomTom 720.
I still laugh at those idiots who follow the directions over cliffs, down railway lines or across fords which are more like rivers, but now I can see a real use for it.
1/ It is right 'almost all' of the time, and is very handy if you are travelling to somewhere totally unknown.
2/ It has a bluetooth hands free phone function, very nice.
3/ It is an MP3 player, and can play your music wirelessly through your car's radio (can also store lots of photos ~ something to look at whilst driving....?)
4/ Automatically tells you if you wander over the speed limit.
5/ Distance to go and arrival time (very handy if you've never done that route before).
6/ It can show you points of interest. I have mine set up to show me where there are LPG stations on route.
7/ Speed camera location alert.
8/ Traffic jam warnings.
9/ Tells you excatly where you are (handy if you breakdown somewhere).
The traffic does seem to be very handy. It can automatically update your route and sends you around accidents and jams. Also, if you go a different route to the one it tells you, it will automatically replot a new route.
As long as you don't believe everything it tells you with blind faith, it is a fantasic bit of kit. I wouldn't be without mine now and since I had it , it has been invaluable.
