Why is My Touchscreen Car Stereo Not Working? 

Many factors can make the car stereo touchscreen not function properly. Below are some of the common reasons: 

Overheating Issue

The touchscreen car stereo will likely stop working when the car gets overheated. Car overheating can result from playing music for a long time or other reasons. 

If overheating is the issue, you must turn off the system and let it cool for a bit. After some time, you can check the touchscreen. The screen will likely start working correctly. But if you cannot turn off the unit, you must use buttons to fix the issue. 

System Having Difficulty Processing

Touchscreen car stereo often fails to function properly when the unit’s software cannot understand your commands. It mainly happens when you are using different functions at once. If functions like Bluetooth, navigation, or similar things run simultaneously, it can compromise the touchscreen’s performance. 

You can fix this issue by closing different running functions at once. But if the touchscreen stereo is still not responding efficiently, you can consider restarting it. 

Calibration Issue

Calibration is a common problem that can compromise the touchscreen stereo’s performance. You should recalibrate the machine by following the guidelines described in the manual to fix the issue. 

Dirty touchscreen

Many times dirt accumulated on the touchscreen makes it unresponsive. But you can fix this issue by wiping the dust using a microfiber towel. Ensure no fingerprint remains on the touchscreen as it can interfere with the performance. 

Major Problems of Touchscreen Car Stereo

It’s important to know about the major touchscreen car stereo problems so you can quickly resolve them. 

Problem 1: Unresponsiveness

A fully responsive touchscreen is fun to use. However, operating a touchscreen can become problematic if it’s not responding well. Unresponsive touchscreen car stereo is not uncommon, but it needs to be fixed. 

A touchscreen with lost calibration will not respond as expected as it will not register the touch pressure accordingly. 

Dust and dirt build-up on the screen can make it unresponsive. Therefore, you must regularly clean the screen. 

Problem 2: Wiring Problem

Many times the touchscreen also becomes unresponsive due to internal wiring issues. In some extreme cases, if the wiring issue increases, you might not be able to power on the screen. 

Sometimes, wiring problems occur due to faulty installation, which is not difficult to fix. Other times the internal wires get loose due to heavy vibration. 

Problem 3: Prone To Physical Damage

Touchscreen helps get the work done quickly, but they are also prone to physical damage. The touchscreen might break quickly if you use them harshly. 

Suppose your car jumps a little too hard on the speed bump. In that case, you might end up with a cracked or broken display. The touchscreen will break even if you accidentally hit it. In addition, prolonged touching can result in scratches. 

Therefore, if you want to use the touchscreen for a long time, you should be extra careful. 

Problem 4: Software Error

Software plays an essential role in the proper functioning of smart touch. Since millions of codes help the touchscreen perform smoothly, the screen will likely develop bugs. 

Your stereo will not work the way it should in such a case. It might start malfunctioning now and then.

Step 1: Remove The Car Stereo

Start replacing the touchscreen car stereo by removing the stereo from your car’s dashboard. Separate the panel using a panel remover. Then remove the screws that are used to keep the stereo placed inside. 

Carefully separate the wires and pull out the stereo. Try to remember the wires because you will have to rewire them at the end. 

Step 2: Dissemble The Car Stereo

Dissemble The Car Stereo

Once your stereo is wire-free, keep it safely in a secure location. Using a screwdriver, start unscrewing the screws on the surface. Then open the front panel. 

The car stereo body has multiple locks that need to be unlocked correctly. Use a panel remover and apply force to unlock. 

Step 3: Remove The Main Wires Of The Screen Panel

Once you have wide open the chassis, you can see everything present inside the stereo. If you carefully look inside, you might find a set of circuits and different wires inside the screen panel. You are required to detach the wires gently. 

Step 4: Disconnect The Touchscreen

Using the same way, you must disconnect touchscreen wires as well. Check the placement of the motherboard. 

If the motherboard is positioned correctly, you might not have to remove it. Otherwise, take out the screws from the motherboard. The idea behind doing this is to disconnect the touchscreen from the motherboard completely. 

Step 5: Remove The Broken Touchscreen

A touchscreen is not attached through screws. Instead, it is attached using glue or any other adhesive. Therefore, you must loosen the glue to remove the touchscreen without any damage. Once you have done it, the LCD will be entirely exposed. 

Step 6: Clean The LCD

After the LCD is completely exposed, you must eliminate all the debris and dust using a gentle cleanser. Use a microfiber cloth for this step to get the best result. Do not clean the LCD too hard as it might damage it. 

Step 7: Install The New Touchscreen

Once you have cleaned the LCD properly, install a new touchscreen. Mount the new component using a high-quality adhesive like double-sided adhesive tape. Cover the component with thin and long pieces of tape for better results. 

Place one side of the tape after peeling it on the sides of the new screen. Then you can peel the other side of the tape as well. Try to align the touchscreen with the panel. In addition, the wires should also be placed correctly. At last, you can place the touchscreen carefully on the panel. Do not rush the process. 

You can apply some pressure to attach the screen to the right place correctly. Try to establish an airtight connection. 

Step 8: Add a Screen Protector

For extra protection of the touchscreen, it’s advised to install a screen protector. The protector will keep the screen safe from scratches and dust. Also, a good-quality screen protector will save you from opening the screen again in the future. 

Step 9: Reassemble everything carefully

At last, you have to connect the wires correctly so the touchscreen can become responsive. Ahold the disconnected wires and connect them the way they were before. Before joining the panel wires to the motherboard, you must join the screen’s wire to the panel.  

Finish the replacement process by screwing the motherboard in the right place. Then you need to close the chassis and reconnect the stereo wires to the car. 

How Do You Reset a Touchscreen Car?

If nothing works and your touchscreen car stereo is still not working, perform a factory reset. If you have an Android head unit, this step will be easier. Use a USB keyboard to do a factory reset. This technique will work even in the case where the screen completely stops functioning.
