The C550 is part of Garmin's StreetPilot line of GPS units. You can retrieve navigational information as well as use Bluetooth wireless capabilities and get FM traffic reports with the C550. Some simple issues you may experience with the Garmin C550 can be resolved with some basic troubleshooting instead of contacting the Garmin support center.
Instructions
1. Turn off the Garmin C550 before connecting to your computer via a USB cable included with the unit. If the unit is powered on before connection, the computer may not detect it. Later, wait for a message to appear on the computer that it is safe to unplug the USB cable before disconnecting it.
2. Check your Bluetooth settings. If you are unable to partner your Bluetooth device such as a cell phone to the Garmin C550, go to the "Bluetooth" option in the C550 main menu. Touch the screen to change the status to "Enable" if it is set to "Disable." Your partnering Bluetooth device must be turned on as well and within 30 feet of the Garmin C550.
3. Change the fuse. If you lose power on the Garmin C550, you may need to change the fuse in the unit. The Garmin C550 uses an AGC/3AG 2-amp 1500 A-rated fuse to operate. On the vehicle adapter included with the unit, unscrew the rounded end and replace the fuse with a new one.
4. Calibrate the screen of the Garmin C550. If the screen is not responding to your touch, you should try to calibrate it. Access the calibration feature by pressing and holding down the "Power" button for one minute. Follow the instructions displayed on screen to calibrate the GPS unit.
5. Update the software of your Garmin C550. Garmin uses its WebUpdater software program to distribute new drivers and maps. You can download the program from the Garmin website to make sure your unit is up to date.
