Question about Garmin Nuvi40lm Nuvi 40lm Lower 48 Gps Travel 010-00990-21
The calibration is so badly off that when I hold my finger down on Top left hand side it sets off the search option
Turn off the Nuvi. Place your finger on the upper left-hand corner of the screen and then push down on the power button to turn the unit on. Release the power button when the Garmin logo appears. Continue to press on the upper left-hand corner of the screen until you see the calibration screen.

Turn off the unit. Then hold down the power button for about 1 minute and the calibration screen will eventually come up.

If you keep holding the button down it will go past the pre-boot mode and you'll eventually come to the calibration screen. Please see this link for more info:

Please see this page for recalibration procedure. If that doesn't work, then then the touchscreen needs to be replaced.

There should be a black dot to press on the calibration screen. Keep pressing the dot as it moves around the screen, you may need to press very firmly and use a stylus until it says calibration complete.
This usually occurs when a unit is dropped or left in extreme temperatures or jammed it a glove box or console with things jammed against the screen. It could also occur if you are touching the screen as you start.
Thanks for using FixYa
