The new Nokia 6110 Navigator sliderphone is the first GPS-enabled Nokia mobile to offer real out-of-the box satellite navigation.

Not only does it have a built-in GPS aerial, but it also comes supplied with inbuilt voice-prompted navigation, and a smartcard with complete UK and Ireland road maps. You don't even need to put in a SIM for it to start telling you where to go.

The difference between this and previous Nokia satnav GPS-equipped phones - such as the N95 and E90 - is that there's no need to download maps at each location, or pay for a full step-by-direction service. You get everything you need in the box. Rather than using Nokia's own Nokia Maps service, the 6110 Navigator uses Route 66's software and Navteq's mapping in conjunction with the built-in GPS antenna.

It's the ease of use of this approach that we found the most pleasing. It really is like having a standalone GPS device in your pocket. And even though it is powered by Nokia's trusty S60 smartphone platform, you can get the road navigation device fired up by simply pressing the large, central, dedicated button.

We tested the navigation facility extensively during a weekend of driving and walking in central England, and were very impressed with its operation. Even when fired up for the first time, it works out your position within a minute or two.

You can then zoom in and out without any fuss using the * and # keys. Just as with a standalone TomTom in-car system, you can pick your destination using postcode or name, and it finds where you are looking to go to without any difficulty or huge delay.

Instructions are clear and precise - and you get a good amount of customisation options. You can choose to navigate by foot or by car, elect to avoid motorways, have maps displayed in 3D or 2D mode, or change colour schemes.

A reasonable amount of points of interest can also be overlaid over the maps. If you want more - you can pay for a higher level of services, subscribing to traffic alerts, for instance, or downloading alternative voices for the spoken instructions. You can, of course, buy further route maps for other parts of the world.
