Sat Nav Buying Guide
Satellite Navigation will help you get from A to B – even if you need to go via C, D and E, without any fuss or tantrums. Most units have large clear displays, show 3D mapping which really resembles the road ahead and are able to locate points of interest such as restaurants and service stations.
Sat Navs use GPS or the Global Positioning System which is a system of 24 satellites in orbit around the earth that allows GPS receivers to pinpoint their location.
Why do I need Sat Nav?
Most people can find their way around with a map, but you can’t read a map on the go and your atlas of Great Britain isn’t much help in towns and villages. Britain’s roads are becoming more and more congested and complicated in layout and restrictions. GPS systems combine knowing where you are with a route planning capability, they can then take the hassle out of navigating providing you with turn by turn guidance to your destination. Even if you take a wrong turn your Sat Nav will know and tell you how to get back to where you want to be. The best systems go further by knowing about useful locations like petrol stations and some even know about the traffic conditions.
How does it work?
The GPS system calculates your location using a minimum of 3 satellites at any one time, these signals are compared with a database of maps within the unit and your current location is calculated and displayed.

Are sat navs distracting to use?
Sat navs take the stress out of driving by guiding you quickly and safely to your destination without the need to snatch a look at your map. Some Sat navs are more distracting than others. For minimum
distractions we recommend choosing a model with a large widescreen, clear, simple and timely visual and audio prompts, easy-to-navigate menus and simple operational features.
Why can’t I find a new build address?
Your sat nav is unlikely to find a newly-built address, you’ll have the same problem trying to get things delivered to a new build estate, – it takes a while for new addresses to make it onto the various systems. Keep trying every few week, it will show up eventually. Consider whether there’s an older address nearby for your sat nav to target instead.
