Garmin Nuvi 50LM Troubleshooting
A few troubleshooting issues for the Garmin Nuvi 50LM GPS device, and some possible underlying causes for the issues.
The back of your GPS feels hot to the touch.
Do not expose the GPS to temperatures higher than 113F. Excessive temperature may cause overheating and malfunctioning of the device. If the battery overheats, place your GPS in a cooler environment and allow the temperature to decrease.
Your GPS reads/speaks "No Signal Found" or it does not accurately find your location.
Check your surroundings. Make sure that you are not inside a parking garage, tunnel, or under anything that may disrupt the signal. Do not let any object, other than the roof of the car, block the GPS unit's signal.
Restart your GPS and allow it time to acquire your location. Sometimes, the device takes several minutes to find the satellite signal.
Your GPS is not generating sound.
Go to your device's settings and select Volume. Verify that the volume is not muted. If the volume is muted, or extremely low, set the volume to an audible level.
Your GPS might have a defective speaker that needs to be replaced. Follow the steps in the Garmin Nuvi 50LM Speaker Replacement Guide to replace the speaker.
Your GPS will not charge.
Depending on the make and model of the car, the 12-volt charger may continue to charge the unit even if the car's ignition is off. Other vehicles require the ignition to be in the on position for the device to charge.
Make sure your charger does not have any exposed wires; This can cause a short in the charger and disable charging.
Your device will only charge if the temperature is between 32F and 113F. Limit the GPS unit's exposure to extreme cold and hot temperatures.
Your GPS might have a defective battery that needs to be replaced. Use the Garmin Nuvi 50LM Battery Replacement Guide to replace your device's battery.
Your GPS is on, but you can barely see the display.
Go to your device's settings and select Brightness. Adjust this setting until your screen is clearly visible.
Make sure your device's battery has enough charge to power the LCD screen. The screen does not work properly if the battery does not have enough charge. Charge the GPS and see if the quality of the display improves.
If the touchscreen has a crack, consider reviewing the Garmin Nuvi 50LM Touchscreen Replacement Guide.
