Car Bluetooth Not Working How To Fix It

Have you ever had a situation where the Bluetooth feature in your car stopped working for no clear reason? When that happens, you can’t pair up your smartphone with the car’s stereo system and use the features that come with it. This can be quite frustrating, especially if your daily driving routine relies a lot on this useful feature. In our previous article, we learned what Bluetooth is and how it works in your car. In this article, we will cover the most common problems causing connectivity issues and ways to deal with them.

Why Is my Bluetooth Not Connecting to my Car?

Sometimes, your smartphone may refuse to pair up with the audio system in your car, or the connection may break up on its own. When this happens, there are several tricks you can use to get it working again. If turning the audio system off and on again doesn’t help, try some of the steps explained below.

Start by making sure that both the smartphone and the audio system are ready for connection. In certain cases, the problem can be as basic as the Bluetooth feature accidentally being turned off. Check the settings for both devices to see if the Bluetooth option is on and that they are in discoverable mode. On smartphones, this is a straightforward job but can be more complicated with the audio system. If you are unsure how to do this, consult your car owner’s manual.

While Bluetooth connections work at distances up to 30 feet, it requires much closer gaps during the pairing process. When trying to pair them up, hold your phone close to the dashboard and the head unit itself. Also, make sure there are no obstructions between the two. Once connected, you can place the smartphone in your. briefcase, or any other place of your choice.

Bluetooth compatibility between devices

In theory, all Bluetooth devices are compatible, making it possible to connect all of them together with no additional steps. In real life, various devices use different versions of this communication protocol, which can sometimes cause pairing issues. If you suspect this might be the case with your setup, try installing a software update for your smartphone. As the latest software version will always work with all older variants, installing the latest version available should do the trick

If the Bluetooth connection in your car cuts out occasionally, you should check several basic things. One of them is making sure that your phone isn’t low on battery. Since Bluetooth draws a lot of power, some smartphones will turn it off while in power-saving mode. You can also check the list of devices connected to your audio system, as some of them might interfere with the connection of your phone. Remove any devices you are not using and check if that makes any difference.

Why Can’t I Play Music Through Bluetooth in my Car?

There are cases where your smartphone connects to the car and appears to work as it should at first. Still, the audio system refuses to play music from your phone, although it allows you to take calls without issues. If you are driving an older car, chances are the root of this problem lies within the audio system itself. When cars first started using Bluetooth, they used a simple communication protocol called a hands-free profile or HFP. Although being able to transfer phone calls through the audio system, this system couldn’t cope with high-quality stereo music. This was because of both hardware and software limitations, made to cut production costs. To stream music from your smartphone, the audio system in your car must support an advanced audio distribution profile or A2DP. In most cases, software upgrades or diagnostic tool interventions can unlock this option.

Why Is Apple CarPlay Not Working?

Eventually, most iPhone users get the dreaded “Apple CarPlay connection failed” message from their infotainment system. In many cases, this happens after updating your iPhone with the latest software version. Dealing with this problem can sometimes be difficult, as it is not limited only to Bluetooth connection issues.

Just like with any other gadget, the best place to start is restarting the device. If you are experiencing any Apple CarPlay issues, turn off and restart the infotainment system. Have in mind that every system is different, so check your vehicle’s manual to see how to reset the infotainment system. You can also reset your iPhone. Just in case.

Another thing to check is if CarPlay is enabled and not blocked. This can be on your iPhone or within the infotainment system. In some cars, you have to enable the CarPlay feature before you can start using it. The best way to do this is by checking your vehicle service manual. If using restrictions on your iPhone, you may have disabled CarPlay by accident. To make sure, navigate through the settings menu until you find the restrictions tab. Scroll down until you find the CarPlay tab, and turn it off.

How Do I Fix my Bluetooth Not Working on my Android?

There are several reasons why Bluetooth may not work on your Android device, although it usually comes down to two scenarios. Procedures are similar for most Android smartphones, as they use similar software and interface. Start by resetting network settings, which you can find within the general management menu of your phone. By doing this, you will return Bluetooth, Wi-Fi, and other network settings to their defaults. With some luck, this simple step will solve your connectivity issue, although you will have to reset all Wi-Fi connections.

There are cases where some Bluetooth applications installed on your smartphone interfere with its operation. To disable them, navigate through the settings menu until you find the Applications tab. Here, select system applications and scroll down until you find one called Bluetooth share. Open the info tab for this application and then clear both storage and cache within sharing options. With this done, move back and select the force stop tab to turn off the application. Repeat this procedure for another application, called Bluetooth or BT Tools. Once it’s done, go back to the home screen and restart your smartphone. After this, the Bluetooth option should work.
