The touch screen is not responding, the only thing it will

Customer Question

The touch screen is not responding, the only thing it will do is when the unit is powered up, i get a notice to update map data. nothing happens when i press ok. if i hit the power button again, i get the set brightness screen, the buttons for that , the cancel and ok work but they just take you back to the map data notice screen. I have taken the battery out for a reboot, this has no effect.

Nuvi 550
Expert:  Richard replied 7 months ago.


Remove the charger from the Nuvi and hold the power button to off for 35 seconds.

Release, then connect the charger and try to turn on the unit and use the screen.

Let me know the results please

Thank you

Can you attempt the following please

  1. Start with the device OFF and unplugged from power
  2. Touch and hold the lower right corner of the screen with an index finger or the eraser end of a pencil
  3. Continue touching and holding the lower right hand corner of the screen then power the device ON
  4. Release the power button when the device powers ON
  5. You will see a new message: "Do you really want to erase all user data?"
  6. Remove your finger from the touch screen when this message displays
  7. Touch Yes

Tell me if you can complete this and if it then works.
