Guiding you from A to B

The emergence of cheap, portable satnav units really has revolutionised travel for most of us. No longer are you destined to spend hours driving randomly around city centres, and even the geographically-challenged now have a fighting chance of making meetings on time.
As the technology has got more advanced, the satnav gadgets themselves have shrunk, and now there are even mobile phones with mapping capabilities built in. When choosing a unit, it's key to decide what sort of features you want – while basic maps are free, many providers charge for add-on services like live traffic information, for instance. If you plan a lot of travelling, it's also worth checking you can easily change country maps – you don't want to discover on the ferry across the channel that you need to buy a new memory card for French maps, for instance.
