These are the devices that rise above your phone's GPS and the free maps you have been using.

The following sat navs are dedicated to giving directions, so will get you from A to B or C to G, if you ask them really nicely.

We've tried to feature devices that straddle a number of price points and offer a bundle of features that will make you want to get in your car right now and just drive. To be honest, we'd be lost without the following recommendations.

TomTom's Via 53 very much sits in the mid-range category of sat navs. It offers connectivity options via a Bluetooth smartphone connection.

Through this connection, you get live traffic updates, can take advantage of hands-free calls and your text messages can also be read out by the device.

When it comes to mapping, the TomTom Via 53 is very good - the 5-inch touchscreen that requires light gestures, while voice control is warrantedEverything is clear and precise.

The design is a bit too chunky, however, and the one-hour battery life is a touch disappointing. Those niggles aside and what you have is a well-specced and connected sat nav that comes at a decent price.

The Garmin Drive Assist 51 is a fine, premium = alternative to getting maps on your phone. If you want a dedicated sat nav that doesn't rely on a handset then the Drive Assist 51 is an excellent choice.

It's wide feature set, ease of use and simple docking means it's a great for those less tech savvy.

The Garmin Drive Assist 51 is laser focused on the navigation experience, and it's one that excels when you're behind the wheel. It's hard to say if it's better than your smartphone, they're very close, but it's certainly no worse.

The TomTom Go 5200 has a 5-inch touchscreen that sits neatly within a sleek plastic chassis. It feels solid in the hand, and the magnetic connection gives a reassuring click into a robust connection with the stand.

The TomTom Go 520 is a smart well built sat nav that's simple to use. It comes with voice functionality - both integration of Siri and Google Now and its own voice system - and some of the best maps around.

It does lack connectivity while on the go which will be an issue for some. You can get around this with a simple hook-up to a smartphone, though.

Battery life is a problem. Up to an hour is quoted but we never really got past the 45-minute mark. In a real-case scenario, though, most will use the supplied charger, given that a sat nav is usually used on longer journeys.

If you are looking for the premium smarts of the TomTom Go 5200 at a smaller price, then this is for you.
