While there are plenty of GPS devices for cars, there are only two that are purpose built for motorcycles - the Garmin Zumo 550 and the TomTom Rider.
Both these devices feature voice guided turn-by-turn directions, loaded maps and hands free phone calls with a Bluetooth enable cell phone. A glove friendly touchscreen and sunlight readable screen are standard. The loaded maps display points of interest (POIs), which are destinations such as ATMs, petrol stations, restaurants and motels.
With these devices you can simply ask the GPS for your destination and you will be directed there by turn-by-turn voice directions through a headset in your helmet. They are also vibration resistant and robust, meaning that they designed to be protected from the vibrations from your bike.
You may also wish to explore a portable GPS device for your motorcycle. Unlike the Zumo 550 and TomTom Rider, these devices are not specifically designed for motorcycle use and you can take them with your on other outdoor activities, such as boating, camping or hiking. These devices will fit to your bike with special mounts that are available for purchase.
Regardless of which motorcycle GPS option you choose, a GPS will open up your travelling choices when you are in the saddle. They will give you a stunningly effective method of navigating and exploring the open road.
If you are looking to purchase a motorcycle GPS device, then you should explore the many online GPS store. With just a little bit of time you should be able to find yourself a GPS for you bike at a cheap price.
