Also, it worked fine just last July. This is first time I got message that computer doesn't recognize it.
Expert:  GeekGal replied 8 months ago.

Thank you for that information. Please give just a moment to research and to type up troubleshooting instructions.

Expert:  GeekGal replied 8 months ago.

Let's start with the easiest possible fixes. Please disconnect the Garmin and power it off. Next restart your computer and login and open the Garmin software. AFTER the Garmin software is open, connect your Garmin. Please let me know the results.

Did that resolve the issue for you? Or do you need more help?

Customer: replied 8 months ago.
I give up, I can't even power down the Garmin, and Garmin software said it didn't recognize the model or serial number. I don't mind if you keep the $5, but please make sure my free trial with Just Ask is over and I am not stuck with a subscription for your services. Please have someone email me to the regard that I have no contract with Just Ask. I would very much appreciate that.

I'm sorry that you're having so much trouble. You should be able to power it off by pressing and holding the power button and not releasing it until you see a prompt to turn it off. It sounds like you may need to do a master reset on your Nuvi.

Note: A master reset will erase all favorites and will restore your device to the default factory settings

  1. Start with the device OFF and unplugged from power
    • To verify the device is powered off and not in standby mode, press and hold down the power button until prompted to turn off the device
  2. Press and hold the lower right hand corner of the display portion of the touchscreen
  3. Power on the device while continuing to hold the display
  4. Remove your finger from the touchscreen when "Erase all user data?" appears
  5. Touch Yes
    • If text language is not in English, this is the button on the right

The device will now reset. Follow the on-screen prompts and then place your device in an area with a clear view of the sky until it acquires satellites.

1Although the master reset will erase all saved favorites, any loaded custom points of interest will remain intact on the device.

Another option to perform a master reset for these devices:

  1. Touch View Map
  2. Touch the Speed icon
  3. Touch and hold the speedometer for approximately 5 seconds
  4. Release your touch when the Diagnostics Page displays
  5. Touch Clear all user data
  6. Touch Yes when prompted to "Erase all user data?"

The device will now reset. Follow the on-screen prompts and then place your device in an area with a clear view of the sky until it acquires satellites.
