These are the sat nav devices that go beyond the GPS in your smartphone and the free maps you've picked up at random road stops over the years. Fold those paper maps up, put your phone away, buckle your seat belt, and get ready to obey the digital voice commands emanating from the sat nav on your dashboard. 

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

To be honest, we'd be lost without the following best sat nav recommendations.

TomTom Via 53

TomTom's mid-range sat nav offers a host of features to tempt smartphone users.

Screen size: 5-inch display | Maps: Lifetime maps Lifetime TomTom traffic | Updates: Updates via Wi-Fi Smartphone messages | Extras: Hands-free calling | Storage: 16GB internal memory

Easy to use
Excellent mapping
Live traffic updates
Only around an hour of battery life
Slow to boot up
Chunky design

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.

Garmin DriveSmart 61

Yes, it's expensive but it's one of the best GPS systems available to get you from A to B.

Garmin Drive Assist 51

A great phone-free sat nav for those who don't want things too complicated.

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.

TomTom Go 5200

The TomTom Go 5200 is a league above most other sat navs, but the price tag is in another world too

Battery lifetime: Up to 1 hour | Vehicle mount: Active magnetic mount | Storage: 16GB | Connectivity: Wi-Fi, built-in SIM

Sophisticated phone integration
Intuitive to use
Screen feels delicate
Voice controls leaves you wanting

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.

It's a wonderful top-of-the-range sat nav that is a pleasure to use, with a bevy of additional features for the frequent driver. If you’re looking for a world-class driving aide, this is the one for you.

TomTom Go 520

The TomTom Go 520 is a super-smart sat nav that will have you navigating in style.

Battery lifetime: Up to 1 hour | Vehicle mount: Active magnetic mount | Storage: 16GB | Connectivity: Wi-Fi, needs a phone for real-time traffic updates

Voice control
Fantastic maps
Battery life is poor
Needs a phone for all the features

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.
