Some sat navs come with bells and whistles: built-in MP3 players that play music through your car speakers, picture viewers to display digital photos, even currency converters for when you're driving in Europe. Here are some of the bonus features.
| Position Plus |
If you're driving in a built-up area or through a tunnel, your sat nav can lose the GPS signal temporarily. Position Plus 'remembers' where you are and calculates your movements while you're out of range, so your sat nav stays useful even in low signal areas. |  |
| TMC | Real-time traffic information helps you avoid jams, diversions, and road closures; TMC is how your sat nav receives it. Look for the TMC logo. |  |
| Gesture Command |
For destinations you visit regularly – such as your home! – Gesture Command lets you tell your sat nav to take you there from wherever you are, with a simple stroke or two on the screen. |  |
| Safety cameras |
The locations of safety cameras are public information – and many sat navs use it to inform you if you're in danger of breaking speed limits when near a camera. |  |
| Dynamic Route Info |
This adds value to your journey, with a host of information about nearby facilities – petrol stations, parking, even tourist attractions. |  |

Expand your sat nav with an accessory or three. Sat navs include
a windscreen mount to keep them in place when you're driving, but many are
useful
away from the car too – so look into a carrying case for when you're
walking around town.
Multi-chargers give you lots of flexibility: a 3-in-1 will let you charge
from a USB socket, normal 3-pin electrical socket, or your car cigarette
lighter.
While a 2-device charger lets you charge two devices at the same
time – so you don't have to unplug
your phone to charge your sat nav.
