With the 2014 Toyota Corolla there is no way to re-calibrate the touch screen when it is not working properly. If Your screen is not working right the first thing that You should do is try to power it off and then back on by pressing and holding the volume knob on the dash. If that does not solve the problem with Your screen then there may be a software issue. You can check the settings menu and see if there are any software updates avaialble for download over the air. You can also check Toyota's website and make sure that You have the latest version. If this does not solve it then You will need to take it to Toyota to let them inspect it.

You can’t calibrate it. Just shove a credit card down the bottom of the button you want to hit. Did it todayand it worked. Jenky, but works. It’snot like you need to change or add devices all the time so.

To calibrate a 2014 toyota corolla touch screen, press the volume button hold it down for 5 seconds. The screen will then light up and be able for touch screen use.

Trying to recalibrate so touch area at bottom of screen works correctly. Touch bottom of screen & the area above is what responds. I should be able to recalibrate it.
Took my Corolla in to get it re-calibrated, was charged $200 they blew some compressed air on the screen then told me it had to be replaced for $1200. There is no way to re-calibrate the touch screen. Better off getting an aftermarket stereo
