The Garmin Nuvi 310 is one of the best-selling GPS devices on the market today. Small enough to be used as an in-car Sat-Nav system or a personal GPS unit, the Nuvi 310 has a 3.5″ touch-sensitive screen and a great user interface.

To see just why it’s such a top selling GPS device, read on for the full Garmin Nuvi 310 review.

The Tom Tom Go 520 is the latest GPS device from Dutch company Tom Tom, perhaps the best known of all GPS device manufacturers (at least in the UK, and if only for their annoying “Doug Doug” TV adverts!). They’ve been around for some time now, but the basic design of the unit hasn’t changed much.

Then again, its user interface is so easy to use, it’s more a case of if ain’t broke, don’t fix it, so they can be forgiven for sticking with a tried and tested formula.

Given that a GPS device’s primary aim is to help you navigate from point A to point B, though, it does make you wonder how much extra Tom Tom can pack into its device in order to warrant a new model. Read on for more on this Tom Tom Go 520 review to find out.

GPS devices have long been designed primarily for car use, with motorbike riders generally forgotten about. Tom Tom aim to change all that, however, with the Tom Tom Rider, a version of its popular Tom Tom Go GPS device that’s designed specifically for motorbikes.

Fitting a GPS device to a bike requires a number of modifications. Firstly, there’s the fact that it’ll be clamped to a bike that hurtles through the streets in all weathers without the comforts usually associated with a car (i.e. a roof and a heater!). Then there’s the added problem of a biker trying to poke the screen with large gloves on.

Add to that the difficulty of trying to see the screen in bright sunshine and the fairly obvious problem of the biker not being able to hear the instructions from the GPS with his crash helmet on, and you can perhaps understand why bikers have traditionally been forgotten about by the GPS manufacturers.

Fortunately, Tom Tom have sold all these problems…
