My Garmin Nuvi 360 Back Light Comes On When The Unit Is Powered On But I Cannot View The Icons Or Menu.?
It is fully charged, has the latest firmware and I have tried to reset it. Although I cannot view anything it appears to “work” because it beeps when I touch some areas of the screen.
You might try a full factory reset, but you’ll lose all your favorites. Cut and paste from garmin.com support…
Note: A master reset will erase all waypoints or favorites and will restore your unit to the default factory settings.
To perform a Master Reset on the nüvi 3xx, follow these steps:
1. Start with the device OFF and unplugged from the power source.
2. Use your index finger to press and hold the top right corner of the touchscreen.
3. Power the device ON while continuing to press and hold your finger to the top right corner of the touchscreen.
4. After the device powers ON, you will see the message: Do you really want to erase all user data?
5. When this message displays, remove your finger from the top right of the touchscreen and touch Yes.
6. The device will now go through the Reset.
7. Follow the onscreen instructions to set up your nüvi.
After the nüvi is set up, if indoors, please go outside to allow the device to acquire the satellite information. Ensure that the device has a clear line-of-sight with the sky.
