Touchscreen Any button, number or letter in the far left edge of touchscreen does not respond when pressed!

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.

The unit may have the problem that befalls the Palm Pilots where something gets under the escutcheon and presses on the touch screen at the edge which overrides any other inputs.

Another possibility is a stuck button. The buttons are usually scanned as a matrix and at startup if a button is stuck that can make unit unresponsive.

Without a logic analyzer and the firmware listing you likely would not get far if one of the logic chips has gone bad unless it can be found using freeze mist and heat gun..

Stuck buttons or touch screen is usually easily found without schematic.

Your touch display is shorting out....BAD

We have three TX's in our family with non-working power buttons. I downloaded the program Au Dodo http://www.freewarepalm.com/utilities/audodo.shtml and simply now use the far left button (button 1) as my 'power' button. It works wonderfully.

I haven't found out how to fix the calibration problem, but power on/off has been totally fixed. Good luck for you.

have the avh 5700 should be close to the same unit. try holding the two center buttons on deck [boost and arrow button] i think then without releasing them push the reset button with a pen ,the screen will close then reopen now let go of buttons should be in the right menu on the first item dont trace the extreme edge come in a little then the second item on the menu screen is the touch section just touch the little plus button on screen if still off try tracing first screen little further from edge. this should fix problem

Try running a piece of paper around the edge of the screen. There may be was something stuck in there, pressing the screen slightly and causing it to not respond to the stylus
