At the British Motor Show today, Garmin showed off its latest sat nav, the Nuvi 500 series (pictured left). This is Garmin's first attempt at a crossover model that can be configured for use by drivers, walkers, bikers (or scooterers) and boaters. Perhaps desinged with British summers in mind, it's waterproof and fuel-resistant (important for bikers, apparently) and comes with both car and bike mounts (see picture below) in the box.

The Nuvi 500 contains UK & ROI street maps, whereas the Nuvi 550 adds a full European map set. It will cost £299 when it goes on sale in September. Detailed topographic and marine charts aren't supplied as standard, although the street mapping does feature digital elevation mapping with shaded terrain contours.

Other features include Bluetooth, a removable battery and support for Wherigo adventure games and a Geocaching player.
