Sounds like the calibration has gone on your touchscreen. Unfortunately there is no fix for the tt like you can with Magellan and garmin.

SOURCE: tomtom one touch screen not working properly

To get it working again, I used the option to change settings and turn the screen 180 degrees. After that at least you can use the buttons again. I have no answer yet for the adjustment trick, but a new touchscreen is not the answer. It may have something to do with buying charts ready on disk, most people do not know if the map they order is the proper one for the model. This can be checked with tomtom home. Once you have turned the screen 180 degrees, you have a better look on where to push to make it work.

Oce I have a better solution, be sure I'll post it.

Touch screen gives wrong letters when touched


Hi, Try using something like a stylus to type in the letters. I've found with gps' that the touch screens aren't that accurate and almost all fingers are too big to properly type in anything and since a stylus (or even a stick) is much smaller it should be more accurate.

The touch screen is not working properly when you


Turn the unit off and make sure the power cable is disconnected as well, get a good SCREEN cleaner. Not the same as Windex or other product. Clean the screen well, you need to get rid of the oils and dirt on the screen. Once you are finished and the unit has been dried off power the unit back up and in one of the submenus you will find a screen calibration option. Use this and you should then be finished and the unit should go where you touch. Hope this helps

After inserting a 1 gig sd card and copying the relevant software across using tomtom home, the unit switches on then goes to a screen that says please wait in about 5 different languages and an egg timer,...


delete everything on the card with windows i.e. double click on my computer select whatever drive letter it has asigned to the memory card in your TomTom unit, then select all and delete. Then restart TomTom home copy relevant software across or use the backup facility and everything worked just fine.

Tom Tom 720 keeps jumping to main menu


Well I finally figured it out for those who might run across this problem.

It seems that when it got hot and expanded the grey bezel around the screen would touch the screen just enough to activate it. I gently pried the bezel up just a bit and it seems to have solved the problem.

No response from touch screen after reset


Hook the Tomtom using the USB cable to your computer. You should see the Tomtom drive under My Computer as a drive letter.

Backup all data from the Tomtom to a folder on your computer. Now select the Tomtom drive and right click, select properties, select tools, and then Check now. Allow the computer to fix any problems with the Tomtom drive. Once this is completed. Remove the USB cable and do a reset. Now turn on your Tomtom and it should work.
