Vexia Econav 435 sat-nav

The new Vexia Econav 435 could cut your fuel bill by as much as 30 per cent, it is claimed, paying for itself within six months.

In addition to helping you get from A to B without getting lost, it also monitors your driving style and offers tips on how to reduce your petrol usage. Just let it know your car, fuel type and how many passengers you've got and it will do the rest.

It'll guide you on the route that's best for fuel consumption, saving both you money and the planet in the process by cutting down your CO2 emissions.

The Econav 435 will be available soon for £169.99, see Vexia for further details.
