Capacitive Touchscreen Is Not Responding on an Automotive Device

Capacitive touchscreens are touch-sensitive screens, often made of glass. The screen senses electrical impulses from the human touch, typically the fingertip. Unlike resistive touchscreens, which sense pressure, a capacitive touchscreen may not respond to styluses or a gloved hand due to the lack of electrical impulses generated. 

Capacitive touchscreens do not have a manual touchscreen recalibration procedure. The capacitive touchscreen is automatically calibrated each time the system boots up.

If your device's touchscreen is not responding accurately, update its system software.

For steps to update the software, see the video tutorial below:
