Finding the best sat-nav device for you depends on a number of factors, including price, available maps and ease of use - and to help you decide we've brought together our favourite stand-alone devices available in 2014.
There are plenty of apps available on modern smartphones, and some of them are free - which makes these devices look a bit expensive by comparison. If you go for a branded device like TomTom or Garmin, you need to make sure you're getting good value for money - so we've put together our top five sat-navs, accessible via the links to the left.
To test each device we looked at the mount, checking both the ease of movement and how easy it is to attach and detach from a windscreen or dashboard. We also looked at screen size and menu simplicity. The best units have interfaces where entering a destination requires minimal interaction.
Another feature we tested is the device's Points of Interest (POI) database. We checked for a restaurant, train station and supermarket, and then entered two postcodes and three addresses. While we were driving we made a wrong turn to test how the sat-nav reacts to missing an instruction.
Bonus points were given for live traffic updates, European maps and Bluetooth hands-free connectivity. Value for money was, of course, a big factor in our final decision as well.
So, what is our best sat-nav to buy in 2014? Well. the Garmin nüvi 3598LMT-D takes the prize - it might be expensive, but it's easy to use and has loads of features, including free traffic updates.
