I've been using a Garmin Nuvi 550 for a few years, simple robust waterproof 8 hour battery life and will mount on a bike or motorbike.
Garmin spec:
With the rugged, waterproof and multi-purpose nüvi 550 sat-nav, you can do it all: drive, hike, bike or boat. nüvi 550 is geared for adventure and is ideal for those who want to go out and explore the great outdoors in every way they can. With a built-in compass and integrated Wherigo™ and Geocaching player, this sat-nav goes beyond navigation to bring the fun of the many family treasure hunts and adventures available online. With detailed European street maps, text-to-speech spoken road and place names and topographic shaded contours, this easy-to-use sat-nav is the perfect companion for navigating your active lifestyle.
Multi-mode for Multi-purpose Navigation
Four bespoke user modes bring customised features for driving, boating, walking and cycling. This flexible navigator combines the advanced navigation and large colour display of Garmin’s in-car sat-navs with the rugged resilience of our outdoor GPS handhelds. Slim and streamlined, it fits neatly into your pocket, bag or backpack, with a removable, rechargeable lithium-ion battery that packs in 8 hours of power. Optional mounts for each mode of transport make it an even better fit. nüvi 550 comes equipped with the latest technology from Garmin, including sophisticated NAVTEQ™ mapping data and waterproof card slot to load different types of mapping such as TOPO for outdoor navigation and BlueChart® g2 Vision® cartography for marine use.
Driving
nüvi 550 makes driving safe, simple and stress-free. Its built-in, unique driver safety system contains details on hundreds of fixed, mobile and temporary speed cameras, variable limit and red light speed cameras across Europe. Smart GPS software uses a patented "corridor" technique of camera validation to bring you only the relevant alerts. The nüvi welcome screen greets you with two simple questions: "Where To?" and "View Maps." Just tap the touchscreen to look up addresses and services and for voice-prompted, turn-by-turn directions to your destination with road and place names announced as you approach. Add an optional traffic receiver accessory for live traffic avoidance using data from real cameras located every 2 mi (3,22 km) along every major route. This live analysis provides real-time incident reporting so Garmin can find the best route around the tailbacks.
Walking and Hiking
nüvi 550 takes walking and outdoor pursuits in its stride, with shaded, contoured maps and a sunlight-readable, waterproof touchscreen. Select the walking mode to activate the built-in compass page, journey track log and integrated Wherigo/geocaching player. Or plug-in optional topographic mapping for routing on road, track and path, with detailed contours, geographic points and shaded terrain.
Wherigo lets you create and play GPS-enabled adventures in the real world. Be guided by GPS technology to physical locations across the landscape and interact with virtual objects and characters.
Geocaching is an entertaining adventure game for the whole family, combining the thrill of a treasure hunt with the discovery of new places. Geocachers hide-and-seek prizes hidden across the landscape using clues posted on the internet and coordinates loaded on their GPS handheld.
Scootering and Biking
nüvi 550 fits comfortably on your scooter or cycle for navigation on 2 wheels. An optional scooter mount provides a secure fixing to cushion against vibration from your travelled terrain. The user interface is simple to control on the move, and you can enjoy clear directions on the go. Its rugged UVA/B and fuel-resistant design make it a trustworthy companion, while the waterproof casing braves all weather to give turn-by-turn directions for the most direct route in the quickest time. Just select the bicycling mode and you’re away.
