A Garmin Zumo is designed for rugged use that often comes with the territory when riding motorcycles. Despite its waterproof exterior, the device may take enough bumps and bruises that it could eventually lock up. If this occurs, you can have trouble powering off the device. Every Garmin, however, comes with a feature allowing you to manually restart it even if buttons do not respond. The unit also allows you to perform a master reset to reset the Zumo to factory settings. Writer Bio
