Here are the reasons and solutions for the malfunction of the left row of buttons on the car navigation system: 1. Loose or poor contact of the sensor pins: Solution: Adjust the pin position and repair the sensor. 2. Damaged sensor with incorrect resistance value: Solution: Repair the sensor. If the car is relatively old and the navigation screen uses a resistive touch screen, replacing the capacitive contacts of the screen can restore normal operation. If the car is relatively new, you can calibrate the touch buttons in the engineering mode settings. 3. Faulty control circuit board, unable to receive or send control signals: Solution: Repair or replace the control circuit board.
I also had issues with my car navigation buttons before, mainly due to poor contact or a damp circuit board. You can try restarting the infotainment system first by holding the power button for ten seconds to force a reboot—sometimes the system just freezes. If restarting doesn’t help, take off the panel and check for any signs of spilled drinks. My friend’s car had cola seep into the button gaps, sticking the conductive rubber and causing failure. Try not to place cups near the navigation area, and avoid using a wet cloth to clean the buttons. If you remove the panel yourself, remember to disconnect the power first to avoid blowing a fuse. If you still can’t fix it, you’ll need to take it to a professional shop to inspect and repair the circuit board.
