In today’s modern vehicles, touch screens have become a vital component of the car’s interior, providing access to various functions and controls. However, like any electronic device, car touch screens can encounter issues that affect their performance.
From unresponsiveness to software glitches, these problems can be frustrating. The good news is that many touch screen issues can be resolved by performing a simple reset. In this guide, we will walk you through the process of resetting your car’s touch screen, helping you regain control and enjoy a seamless driving experience once again.
Understanding Your Car’s Touch Screen
Different types of touch screens in cars:
- Resistive touch screens: These touch screens use pressure to detect touch and are typically found in older car models. They require more force to register input.
- Capacitive touch screens: Common in modern vehicles, capacitive touch screens use the electrical properties of the human body to detect touch. They are more responsive and offer multi-touch capabilities.
The basic components of a car touch screen system:
- Display: The visual interface where information and controls are presented.
- Touch sensor: Located on top of the display, it detects touch inputs and translates them into commands.
- Controller: The brain of the touch screen system, it processes touch inputs and sends instructions to the vehicle’s computer or relevant components.
- Wiring and connectors: These connect the touch screen components to the vehicle’s electrical system, allowing for communication and power supply.
Understanding the type of touch screen in your car and its components will help you troubleshoot and perform the necessary reset more effectively.
Identifying Common Touch Screen Problems
Unresponsive touch screen:
- Touch inputs not registering or delayed response.

Performing a Soft Reset
A soft reset is a simple and non-intrusive method to address minor issues with your car’s touch screen. Follow these steps to perform a soft reset:
Locate the reset button:
- Check your car’s manual or documentation to find the location of the reset button.
- Typically, the reset button is a small, recessed button located near the touch screen or in the control panel.
Press and hold the reset button:
- Using a pointed object like a paperclip or a pen, gently press and hold the reset button.
- Hold the button for about 10-15 seconds or until you see the screen turn off or display a restart symbol.
Release the reset button:
- Once the screen turns off or shows the restart symbol, release the reset button.
- Give the touch screen a few moments to restart and initialize.
Performing a soft reset will allow the touch screen to reboot and clear any temporary glitches or unresponsive behavior. After the reset, test the touch screen to see if the problem has been resolved. If the issue persists, you may need to consider performing a hard reset or seeking professional assistance.
Performing a Hard Reset
If a soft reset doesn’t resolve the touch screen issues, a hard reset may be necessary. Please note that a hard reset may vary depending on the specific car model and manufacturer. Before proceeding with a hard reset, ensure you have reviewed the vehicle’s manual for any specific instructions or precautions. Follow these general steps for performing a hard reset:
Turn off the car:
- Ensure the vehicle is parked and the engine is turned off.
- Safely engage the parking brake for added security.
Disconnect the car battery:
- Locate the car battery, usually located in the engine compartment or trunk area.
- Use the appropriate tools to loosen and remove the negative (-) battery terminal.
- Carefully detach the negative cable from the battery terminal.
Wait for a few minutes:
- Allow the car to sit without power for approximately 5-10 minutes.
- This will help discharge any residual power and reset the touch screen system.
Reconnect the car battery:
- Reattach the negative cable to the battery terminal.
- Use the appropriate tools to tighten the negative (-) battery terminal securely.
After reconnecting the car battery, start the vehicle and check if the touch screen functions properly. It may take a few moments for the touch screen system to initialize. If the issue persists or if you are uncomfortable performing a hard reset yourself, it is advisable to consult a professional technician or contact the car manufacturer’s support for further assistance.
Calibration and Software Updates
Calibrating the touch screen after a reset:
- Once the touch screen has been reset, it’s recommended to perform a calibration to ensure an accurate touch response.
- Refer to your car’s manual for specific instructions on how to calibrate the touch screen.
- Typically, the calibration process involves accessing a settings menu or performing a series of touch gestures on specific calibration points displayed on the screen.
Updating the touch screen software/firmware:
- Outdated software or firmware can contribute to touch screen issues.
- Check the car manufacturer’s website for any available software or firmware updates for your touch screen system.
- To download and install the updates onto a USB device, follow the steps that are supplied.
- Connect the USB drive to the vehicle’s USB port and follow the on-screen prompts to initiate the software/firmware update.
Calibrating the touch screen ensures accurate touch response, while updating the software or firmware can introduce bug fixes and improvements that enhance the touch screen’s performance. Regularly checking for updates and performing calibrations can help maintain a healthy touch screen system.
Troubleshooting Further Issues
Despite performing a reset, there may be instances where touch screen problems persist. In such circumstances, take into account the troubleshooting techniques below:
Consulting a professional:
- If the touch screen issues persist or reoccur frequently, it’s advisable to seek assistance from a qualified automotive technician.
