Thinnest GPS ever

Magellan unveils the Maestro: size zero satnav

GPS pioneers Magellan may have fallen behind the likes of TomTom and Garmin in the satnav race, but they've pulled a bit of an ace out of their pockets - the world's thinnest GPS device.

It's called the Maestro, and it's a mere 17.8mm thick - so it's a pocket-sized device that can be taken out of the motor and used on foot if necessary. But it doesn't skimp on the features to keep its waistline small - there's a 4.3-inch screen here, which is as big as anything you'll see on a rival device.

There are three new models in all. The Maestro 4200 is the entry-level model, costing about £190 and coming with maps of the UK and Ireland. One step up is the 4215 (£230), which covers the whole of Europe and over a million Points of Interest. Topping out the range is the 4245, which has full Euro coverage plus live traffic updates, text-to-speech and Bluetooth for hands-free calling; it will cost about £300. Look out for all three models in October.
