Car sat nav systems are becoming increasingly sophisticated – you may find some new sat nav features useful. Many sat navs now feature voice recognition, so you speak your intended address, which avoids typing.
Lane-guidance technology – which shows you road signs on screen, and the lane layout as you approach junctions so you know where you should be positioning yourself in advance – is now a common feature, and can be very useful if you’re on very unfamiliar roads. And most sat navs also allow you to specify routing options, so you can avoid low bridges, motorways or narrow roads, for example.
Which? conducts a number of route accuracy tests to see if our satellite navigation devices can cope with motorways, country roads and built-up areas.
We purposely check whether sat navs can recognise newly built addresses, and assess how well they direct you should you need to conduct two manoeuvres in quick succession. This is important if, say, a driver needs to drive through two mini-roundabouts in a busy area and won’t have time to correct mistakes.
