How do I fix when I touch a key to put in information and it prints a different number or letter than the one touched


Here is a way to recalibrate the touchscreen without having to go through the menus:

If your Nuvi has the problem that when you press one key but another key is highlighted, then either your touchscreen is defective or it is miscalibrated.

For example, pressing the letter "A" on the QWERTY keypad, actually highlights the letter "S" or "Q" or "Z". On the non-QWERTY keypad, this may show up as "B".

Method #1: If you can get to the main menu, press the "wrench/tools" icon and then the "Display" icon. Now press the calibrate screen button and go through the entire procedure of pressing each dot as it appears on the screen until it says "Done".

Method # 2: Follow this procedure if you can't get to the main menu or any menu thereafter.

First, turn the unit OFF.

Nuvi 3xx & 6xx Series: Hold down the on/off power button and don't let go of it.

On the screen it will say "Pre-boot mode"..... keep holding the button down..... after some time you will eventually come to a screen with dots. If the screen says "Loading" and does not go to to the calibration screen with the dots, you will need to connect the Nuvi to a PC with a USB cable and rename the file "GUPDATE.GCD" within the Garmin directory to "GUPDATE.OLD". Once the file has been renamed, repeat the above procedure.

Once you reach the calibration screen, now you can let off of the on/off power button. Go through the entire procedure of pressing each dot as it appears on the screen until it says "Done".

Nuvi 2xx/2xxW Series: Turn the Nuvi off. Place your finger on the upper left-hand corner of the screen and then slide the on/off power switch to the left and hold until you see the calibration screen. Note: Some 2xxW models require the procedure below for the 7xx.

Nuvi 7xx Series: Turn the Nuvi off. Touch the screen anywhere and keep your finger there while moving the on/off switch to left (don't wait for Garmin logo to come up) and then quickly moving the switch the right (lock position). After a short while, you will reach the calibration screen. Go through the entire procedure of pressing each dot as it appears on the screen until it says "Done".

Nuvi 8xx Series: Turn the Nuvi off. Remove the battery from the Nuvi for at least 10 seconds. Press and hold your finger on screen, while putting the battery back in. The Nuvi will boot-up and you should see the text "Pre-boot Mode" appear on the screen. Continue pressing on the screen until pre-boot goes away and the progress bar appears. Now remove your finger. After a short while, you will reach the calibration screen. Go through the entire procedure of pressing each dot as it appears on the screen until it says "Done".

Nuvi 11xx, 12xx, 13xx, 14xx, 16xx, 24xx, 25xx Series: 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.

Once completed the Nuvi will display Calibration Complete

This will recalibrate your touchscreen to the LCD display.

If this doesn't resolves your problem. then your touchscreen may be defective.

System software missing


Just had this problem over the weekend. I emailed Garmin and received a zipped file to reinstall original software with step by step instructions. It took about 6 minutes to do and works perfect again. Go to the Garmin website and email "software system missing" issue to support email address. Have your serial # handy. I received a reply in 1 business day. Hope this helps!

Garmin Nuvi 350 Calibration Issue


Turn the unit off. Press and hold down the power button and keep holding it. You will see the screen light up and it will say "pre-boot mode". Keep holding down the power key. It will then say "booting". Keep holding the power button down. You'll then come to the calibation screen. Select the dots and you'll be back in business.
