Causes Of BMW No Source Available

The no source available is one of the common issues with the BMW, which many owners encounter. It is frustrating to deal with, especially in the case of a no audio source available message, which prevents you from listening to music or making hands-free phone calls. 

But it is important to know the reasons why this issue happens to determine the right course of action you need to take. For example, this issue may be linked with a faulty head unit. Your head unit is the central control panel for your car’s audio system. It controls your volume, and it allows you to switch from one audio source to another. Moreover, you can see information on the audio playing on your system.

However, when the head unit is faulty, then it cannot connect to audio sources and it fails to detect any connection, if there is any. Thus, this leads to a no audio source available error.

Another reason for the no audio source available problem is with your connection or wiring. There are many components in your audio system such as the amplifiers, speakers, and your head unit. These are all connected by a series of connectors and wires.

Hence, if there is a problem with any of these connectors, you will encounter problems with using the audio system properly. For instance, a broken wire or loose connector can cause your audio system to display a no audio source available, as well as malfunctioning issues.

You may also be encountering problems with your USB connection or Bluetooth. Most BMW vehicles enable you to connect your devices to an audio system via the USB or Bluetooth. So, if you have issues with your connection, then your audio system is unable to connect to or detect any audio sources. 

If you have a device that is not paired properly, or perhaps your software is outdated, then this issue may arise. Or, you may have a malfunctioning device, as well.

It is also important to note that a problem with your speakers or amplifiers can lead to this connection issue. Since your amplifier boosts audio signal from your head unit and then sends the signal to your speakers, a faulty amplifier prevents any sound from being produced. Thus, you may see the no audio source available message.

The same holds true with damaged speakers or if these are not working properly. There will be no sound produced, and this leads to a no source available issue.

And lastly, you may be encountering a no source available problem when you have a software issue. As with any electronic device, your vehicle’s audio system runs on software, which also controls the functions. So, in the case of a software problem, you may also have a malfunctioning audio system and notice the no source available error. You may either need to update your software or do some bug fixes.

How To Fix BMW No Source Available

If you are wondering how you can fix these problems with having no source available in your BMW, the following are some steps to try.

1. Check your head unit.

In the case of a faulty head unit, you may want to make sure that it is replaced or repaired. But you can also start by checking if the unit is even turned on and you do not have the volume turned to the lowest setting.

2. Inspect connections and wirings

When you have loose connections or some wire damages, you first have to address this problem to make sure that your audio is able to detect or connect. If the wires are broken, then you need to have these replaced by a professional.

3. Check your USB or Bluetooth connection.

You need to make sure that you have your device paired properly with your audio system. It is also worth mentioning that you may need to update your software, which can cause this no source available issue.

4. Inspect your speakers and amplifiers

As we have mentioned earlier, having issues with your amplifiers and speakers can cause the audio to go out. This is why there is no sound produced, and you are unable to play music in your vehicle. Check if there are no damages to your speakers, and if there are issues, you may have to get this component repaired or replaced by a specialist.

Other things you need to check include the audio system’s software, which may need to be updated or have any bugs fixed. Or, you can also check the fuse to your audio system, which may have been blown. Replace any blown fuse and make sure you get a new one with the same amperage.

Lastly, you can also do a simple restart of your vehicle. Sometimes, this does the trick, which is the simplest solution you can do. 

Yet, if none of these tips help, the next thing to do is to take your vehicle to a mechanic to have the problem properly diagnosed and addressed by a specialist.

Wrap Up

When dealing with a BMW no source available issue, there are many things you can do – but it is always good to start by determining the actual cause of the problem. By doing so, you can provide appropriate troubleshooting methods that will deal with the issue once and for all.
