How To Fix A Touch Screen Car Stereo | Step By Step Fixing Guide

Last Updated on February 16, 2022 by Motorist Care

Smart touch screen car stereos are far more convenient to use than their analog counterparts. They allow you to change the stations or control the volume just by touching with your fingertips instead of turning knobs. Some are even fitted with advanced features like GPS, video streaming, phone integration, and more!

Unfortunately, they aren’t immune to problems. The touch screen feature is often the first thing to start malfunctioning. Don’t be disheartened if you’ve accidentally broken the screen or if it has suddenly become unresponsive.

We’re going to tell you exactly how to fix a touch screen car stereo. So, instead of buying a new model, you can try fixing it all by yourself!

What Are The Major Problems of Touch Screen Car Stereo?

Let’s learn a bit about the major problems of touch screen car stereos. It’s important because you will be aware of the issues you may face in the future and be able to quickly figure out how to resolve them.

Problem 1: Unresponsiveness

The touchscreen is only fun when it’s highly responsive to your fingers. But when the screen doesn’t respond, no matter how many magical spells you cast with your fingers, it can get really annoying.

Unfortunately, it isn’t uncommon for touchscreen car stereos to become unresponsive. It can happen due to several reasons.

For instance, if the screen has lost its calibration, it won’t respond as expected as it won’t be able to register the touch pressure correctly.

The build-up of dirt and dust can also cause the touchscreen to be unresponsive. If you do not clean regularly, these filths can even damage the component for good!

Problem 2: Wiring Problem

If there is an internal wiring issue, your touchscreen will fail to work. In some cases, you won’t even be able to power it on. This can occur due to faulty installation, which shouldn’t be that hard to fix. Sometimes, heavy vibration can cause the wires to loosen up.

Problem 3: Prone To Physical Damage

Touchscreens are pretty fragile, so they are very prone to physical damage. They can break quite easily. For example, if your car jumps over a speed bump a little too hard, you’re likely to end up with a couple of cracks or, in the worst-case scenario, a broken display!

If you accidentally hit the screen, it’s going to break too. Besides, prolonged touching can create scratches which can lead to significant damage later on. You’d have to be extra careful when using them if you want them to be in one piece for a long time.

Problem 4: Software Error

Smart touchscreen car stereos rely on software to function properly. Millions of codes allow them to perform as they do. It’s common for the software to have bugs and errors. When that happens, your stereo won’t work as expected. It will start malfunctioning until you find a way to fix the software issue.

These are the most common issues of a touchscreen car stereo. We haven’t covered all of them, so you might come across something that we haven’t discussed.

Guide To Fixing An Unresponsive Touch Screen Car Stereo

Here is a couple of things you can do to fix an unresponsive touchscreen car stereo.

Step 1: Try Rebooting The Stereo

Before you attempt anything, reboot your infotainment system. Rebooting often has the miraculous power of fixing technological devices, so you might get lucky! Most devices can be rebooted by pressing and holding the power button for 5 to 10 seconds.

Step 2: Clean The Touchscreen Properly

Try giving your touchscreen a good old-fashioned cleaning. Remember to be gentle with the process because you don’t want to damage the screen.

Before you do anything, clean your hands. Then proceed to remove the old screen protector. Afterward, dip a clean cloth in a screen-cleaning solution and gently rub it on the screen. When you’re done, apply a new protector. This might do the trick!

Step 3: Perform A Clean Factory Reset

As a last resort, you can perform a factory reset to repair your device. It’s easier if you’ve got an Android head unit. Even if the screen is completely unresponsive, it’s possible to perform the task using a USB keyboard.

A hard factory reset will solve any software-related problem and fix the calibration as well. So, this should help with car stereo touch screen repair. Most of the stereos come with manuals that will instruct you on how to perform a factory reset.

Necessary Tools:

Here are the tools you’re going to need to complete the entire procedure. So, make sure you have them all within your reach.

  1. Appropriate screwdrivers
  2. Panel remover
  3. Clean microfiber cloth
  4. Screen Cleaner
  5. Double sticking tape
  6. A new screen paper

Step 1: Remove The Car Stereo

The first step is to remove the car stereo from your car’s dashboard. Grab the panel remover and use it to separate the panel. Then unscrew the screws that are used to keep the stereo placed inside. Before pulling the device out, carefully separate the wires. Take note of the cables you’re removing because you will be rewiring later.

Step 2: Dissemble The Car Stereo

Now that the stereo is all free of wires- place it in a safe and secure location where you can freely work on it. Pick up your screwdriver and start unscrewing all the screws that you find on the surface. Then open up the front panel.

You will notice numerous locks on the body of the car stereo that you will have to unlock. This can be done by applying a little bit of force in the right direction. You can use the panel remover too.

Step 3: Detach The Main Wires Of The Screen Panel

After the chassis is wide open, you will be able to see everything inside the stereo. Take a look inside. You must find a set of circuits and several wires that are going right to the screen panel. Now, gently detach these wires.

Step 4: Disconnect The Touchscreen

You must disconnect the wires that are connected to the touchscreen the same way. Depending on the placement of the motherboard, you may or may not have to remove the screws from the motherboard. Make sure the touchscreen is completely disconnected from the motherboard.

Step 5: Remove The Broken Touchscreen

The touchscreen is usually attached using glue or an adhesive instead of screws. So, you’re going to have to loosen the adhesive before removing the screen. As soon as you’re done, the LCD will be completely exposed!

Step 6: Clean The LCD

Now, clean the LCD using the screen cleaner gently to get rid of all the residual dust and debris. The microfiber cloth will come in handy so use that to get the best results. You don’t want to press too hard, though.

Step 7: Install The New Touchscreen

After you’re done cleaning the LCD, now is the time to install the new touchscreen. You should use a high-quality and strong adhesive like double-sided adhesive tape for mounting the new component. Cut the tapes into thin and long pieces for getting the best results.

Then peel one side of the tapes and place them on both sides of the new screen. Afterward, peel off the other side. Now, make sure to align the screen with the panel perfectly. The wires must be aligned correctly as well. Then gently place the touchscreen carefully on the panel.

You may have to apply a little bit of force to attach the screen correctly. Leave no room for air to enter because the connection must be airtight!

Step 8: Add a Screen Protector

Before reassembling everything, make sure to add a screen protector to ensure extra protection from dust and scratches. This will save you the trouble of opening up everything again just to apply a screen protector later.

Step 9: Reassemble everything carefully

Remember how you disconnected everything? Now you’re doing to do the same thing, only in reverse! Grab ahold of those wires and reconnect them again. Make sure to connect the screen’s wires to the panel before joining the panel wires to the motherboard.

Screw the motherboard in place. Then close the chassis. Afterward, you must reconnect the stereo wires to the car.

That’s it, you’re all done, and your new touchscreen is ready to be used!
