The head unit, often considered as the "brain" of a car stereo with dvd player, is a critical component that controls the functionalities of your vehicle's infotainment system. It's the part of the car you interact with the most, whether you're tuning the car audio touch screen, navigating with the GPS, or adjusting your sound settings.

However, like any electronic device, it can sometimes encounter issues such as freezing, lagging, or unresponsiveness that require a system restart. In this in-depth blog post, we'll walk you through the detailed process of restarting your bluetooth carplay head unit, helping you troubleshoot minor issues without needing a trip to the mechanic.

Step 1: Turn Off the Carcar stereo

The first step in this process is to ensure your car is completely turned off. This doesn't just mean turning the key to the 'off' position or pushing the 'stop' button on keyless ignition cars; it means turning off all the systems. 

That includes the lights, air conditioning, and any other electronic systems that might be running. This step is crucial as it ensures that the bluetooth android auto head unit and other electronics are not receiving any power, preparing them for a proper restart.

Step 2: Disconnect the Battery

Once your car is completely off, the next step is to disconnect the car battery. This might sound intimidating, especially if you've never done it before, but it's a straightforward process. First, open your car's hood and locate the battery. It's usually quite easy to find. 

Once you've located the battery, you'll want to disconnect the negative terminal. The negative terminal is typically marked with a "-" sign and is connected to a black cable. Use a wrench to loosen the bolt and carefully remove the cable from the terminal.

After disconnecting, wait for about 10-15 minutes. This waiting period allows all the residual power in the car's electrical system, including the bluetooth car radio touch screen, to dissipate, effectively resetting the system.

Step 3: Reconnect the Battery

Once the designated waiting period has elapsed, it is now the appropriate moment to re-establish the connection with the battery. Take great care as you rejoin the negative cable to the corresponding terminal, and proceed to firmly secure the bolt using your wrench. 

It is crucial to verify that the connection is stable and the cable is not in any way loose. By carrying out this process, you will effectively reinstate power to all the systems within your vehicle, encompassing the android auto dvd player.

Now, commence the process of starting your car in the usual manner. As the vehicle powers up, take a moment to inspect the head unit. You should observe that it has undergone a reboot and is now showing either the manufacturer's logo or a startup screen. With any luck, the problem you were encountering has been successfully addressed, and the system is now operating as it should be.

Step 5: Check the Settings

It's crucial to remember that following a system restart, certain settings on your touch screen radio with navigation may have reverted to their factory defaults. This could encompass preset radio stations, audio preferences, Bluetooth pairings, and navigation configurations. Allocate some time to review these settings and adjust them to align with your preferences.


Restarting your bluetooth car stereo is a simple yet effective troubleshooting step that can resolve some common issues. However, if you've followed these steps and your head unit is still not functioning correctly, it might be indicative of a more serious problem that requires professional attention. 

In such cases, it's always best to consult with a professional or your car's manufacturer. Remember, proper and regular maintenance can prevent many issues, prolonging the lifespan of your car audio stereo and ensuring you enjoy a smooth and enjoyable driving experience.
