Vauxhall car and van owners can now enjoy the benefits of satellite navigation at less than a third of the price of factory-fitted systems on new cars, thanks to a link up between the carmaker and TomTom.

Regardless of model or age of your vehicle, the latest GO 300 version of the TomTom portable navigation aid is now available as an accessory from Vauxhall’s UK retailers for £369.99.

It is mounted on an adjustable bracket that sticks to the windscreen via a suction pad and so can be easily transferred from car to car by drivers who have use of more than one vehicle. It has a four-hour battery life the unit, but it can be topped up using a 9V socket.
