The TomTom One classic is a simple and effective sat nav that will get you from a to b.

This device plugs into the cigarette lighter in your car and charges from that. It almost instantly finds the satellite and gives you precise and good directions.

I have used the TomTom one all around the country and it has worked well everywhere. From the small winding streets of Cornwall and Devon to the big motorways and in cities such as Nottingham, Leeds and London.

The only time that it can get confused is when you drive on roads underneath other roads. It often thinks you are on a different road to the one that you are on and gives you some strange directions.
Another little problem it has is occasionally it tells you to 'keep right' or 'keep left' when it means turn right or left and vice versa. The simple solution to this is to look at the simple and easy to read map. On the map it changes the colour of the roads you go on so that you can quickly tell where you need to go if the spoken directions do not suffice.

You can programme in your home location so you can quickly and easily navigate home. You can also customise features such as the voice of the person talking (I use an Irish woman). The car icon can also be changed to pictures of different cars and the background colours can be changed.

The TomTom one tells you where speed cameras are but would need updating regularly which can be done by connecting it via usb to your computer

All in all this is a good and simple to use sat nav. I would recommend this as a cheap and cheerful, yet very capable product.
