The Garmin Zumo 550 is a type of GPS device. Unlike standard GPS devices that are used inside cars, trucks or vans, this particular model is made especially for motorcycles. You can mount the Zumo 550 on your motorcycle and then use it as you travel from place to place. Whether you're riding across town or taking a cross country road trip on your motorcycle, the Garmin Zumo 550 can get you there. If your Zumo 550 won't turn on, however, you'll have to do some troubleshooting.
Check to see that you're pressing the power key to turn on your Zumo 550. The power key is located on the right side of the device.
Plug your Zumo 550 into your motorcycle's power source.
Turn on your motorcycle. This will charge the battery on your Zumo 550. If it's not fully charged, the device may not turn on.
Regulate the temperature of your Zumo 550. Some GPS devices won't turn on when exposed to extreme temperatures.
Press and hold the power key for one minute. This will calibrate the screen and help it turn on or unfreeze if you're having trouble.
