Don't get lost when buying a GPS system

A growing number of riders rely on GPS technology to help make their road trips more efficient and enjoyable. But it's easy to get lost trying to choose from all the available makes and models. Here are some tips.

How it works
GPS, the global positioning system, consists of a group of satellites that transmit low-power radio signals to Earth.

Once picked up by your own GPS unit, those signals allow you to determine your location, figure out how fast you’re moving, and calculate how long it will take you to arrive at your destination.

While many handheld GPS units can be adapted for use on a motorcycle, they’re primarily designed for outdoor recreation like hiking and may not be fully weather resistant. It may be best to look for GPS units designed specifically for motorcycles.

Weather resistance. Look for a unit rated for outdoor use and sealed against moisture. Such a device will also better protect against grime, dust and other conditions encountered on the road. GPS units are typically made with a rugged plastic housing that’s resistant to UV rays and fuel spills.

Shock resistance. GPS models designed for motorcycle use are built to stand up to the rigours of road vibration. Special mounts are designed to isolate them from vibration, using rubber damping.

Sensitivity. While this was a bigger issue only three or four years ago, Tim points out that most new motorcycle GPS units can now receive a strong signal and get it quickly. Highly sensitive microchips effectively register signals while you are riding around high buildings or in dense woods.

Ease of use. The best motorcycle GPS units are easily operated via a touch screen and have glove-friendly controls.

Visibility. Screen size isn’t nearly as important as screen quality to get the full effect of graphics and readouts. Compare models by looking at them from different angles and under different lighting to gauge how well you can read them.

Maps and routing tools. New models feature pre-loaded maps of North America. Map updates are typically offered on an annual basis and range from $75 to $100 per update.

Many motorcycle GPS units feature what is commonly referred to as multi-destination routing. This allows you to plan a route that includes multiple “waypoints” between the start and end of your ride.

Advanced features. GPS units can include a Bluetooth wireless headset you can install inside your helmet to receive navigation audio prompts. The same technology enables hands-free calling. Or listen to satellite radio, live traffic and weather reports with optional subscriptions.

Popular models and prices. The two big manufacturers of motorcycle-specific GPS systems are TomTom and Garmin. Basic models from each range from $500 to $600. Expect to pay $650 to $750 for models with advanced features.

“Follow these guidelines,” says Tim Flight, “and buy the GPS system that best suits your needs and fits your budget.”
