For most owners of caravans and motorhome, a satellite navigation system is a welcome edition to their holiday equipment. If you’ve not made the decision to buy one until now, here’s our top devices. First off, let’s look at the budget end of the market with the Navman S100. Prices online range from just £89 to £170 including delivery. Although it’s in the budget range, the Navman still comes with plenty of features including a 4.3 inch widescreen format touchscreen, 1 Gigabyte of hard disk space and ‘text to speech’ which will read out road names to you as you drive. The Navman also has pedestrian mode, for when you’ve pitched up and want to investigate the local area on foot. It also comes with the Traffic Message Channel to keep you up to speed with the travel news in your area and warn of any potential hold ups on the way to your destination. It can also give you up to the minute weather forecasts!
