If you're lucky enough to be able to afford a European break this summer than something you should be packing in your suitcase is the TomTom XL Live sat nav system.
The system supports LIVE services which keep you informed of all the driving news throughout the UK, Germany, France, Switzerland, and the Netherlands. It also offers maps of 42 European countries. The LIVE services will set you back £7.99 a month, but for this you get High Definition Traffic info, safety alerts, Safety camera alerts, and TomTom fuel prices, giving you the cheapest fuel in your area. You also get their IQ route technology which gives you the best route for a particular time of day or week.
The unit retails for £249.99 and will be available in June.
