TeleNav for Blackberry
TeleNav has been available on multiple Blackberry handsets for some time and is a slick sat nav system with millions of business listings including hotels, restaurants, Wi-Fi hot spots and petrol stations while its map updates are free and automatic.
Price: from £4.99/month;
Proof that you don't have to spend a fortune to reach your destination comes in the form of Binatone's budget G350 sat nav. With a decent colour screen, clear instructions and a full postcode search, it has everything you need and no superfluous features plus, unlike certain TomTom models, you won't need to fork out for endless extras either.
CoPilot Live for Android
Although free Google Maps navigation for Android phones has just been announced, it's currently only available in the US. In the meantime, CoPilot Live is the best way to turn your handset into a sat nav with a slew of useful tools; a network connection for realtime traffic alerts, five days' weather forecats and a location-sharing service called CoPilot LiveLink.
Mio Navman Spirit 500
An excellent all-rounder. With a 4.7in screen, a GPS link to the ATIS service to keep you abreast of incidents and Explore mode offering places to visit in your vicinity, it's a great middle-of-the-road buy.
With an impressive widescreen display and smart software, the 3310 max is a topnotch device at an attractive price. Its MyRoutes technology aims to calculate your journey as accurately as possible taking into account your driving style and average speed. The cherry on top, though, is the fact it includes full European maps.
TomTom Go 940 Live
The TomTom Go 940 Live won't appeal to drivers on a budget but it's packed with features. Internet searches, a safety camera database, rapid updates and weather information are jammed into a sleek package. The downside is, after shelling out the best part of £400, you face a monthly subscription.
Blacks Sat Map 10
Enjoy the great outdoors without the risk of getting lost, thanks to this waterproof, shockproof handheld sat nav from Blacks. Whether you're skiing, trekking or just out for an afternoon's amble, this device tells you exactly where you're meant to be going and its eight-hour active battery life should last longer than you do. It boasts an electronic compass and comes with National Parks maps preloaded. Perfect for those who want to cheat at orienteering.

Garmin Edge 705
If your mantra is two wheels good, four wheels bad, the Garmin Edge 705 is the digital mapper for you. Designed for cyclists, it combines maps and GPS with a heart rate monitor, speedometer, distance tracker, and it records what you've covered so you can analyse your form later.
TomTom on iPhone
With smartphones making inroads in to TomTom's market, it was only a matter of time before the sat nav giant brought out its own app. It offers the comprehensiveness and simplicity of a traditional Tom- Tom unit plus the convenience of having it on the iPhone. Although it's not essential, the accompanying car kit (£99.95) enhances the GPS performance and charges your phone too.
Price: £59.99 (UK) £79.99 (western Europe)
