Most auto GPS devices are not designed to withstand the forces of Mother Nature. This poses a problem for motorcycle owners who want a great navigation system. Enter the Zumo. Designed to be glove friendly, water-proof, and designed with plastics that are more resistant to UV rays and fuel vapors, the Zumo is designed to be out in the open air with you.
While the extra protection does come at a cost, that cost is likely less than replacing a traditional auto GPS not designed for outdoor use. Other motorcycle friendly functions include fuel level warnings with the ability to quickly route to you to the nearest fill-up station, as well as the ability to plan routes ahead of time on your computer and share those routes with other riders.
