If you own a BMW car, you may have encountered the “No Source Available” error message on your display screen.
This error means that your audio system is not receiving any sound from the radio, CD player, or other sources.
It can be frustrating, especially if you enjoy listening to music or podcasts while driving.
Fortunately, there is a simple way to fix this problem by resetting the audio system. In this article, we will explain what causes the error, how to reset the audio system, and what to do if the problem persists.
What Causes the “No Source Available” Error in BMW?
The exact cause of the “No Source Available” error is not clear.
Some BMW owners have reported that the error occurred after a software update, while others have experienced it randomly.
According to a discussion forum, the error may be related to a glitch in the iDrive system, which controls the audio and navigation functions in BMW cars.
The iDrive system may fail to communicate with the audio sources, resulting in an error message.
How to Reset the Audio System?
The easiest way to fix the “No Source Available” error is to reboot the iDrive system. This will clear any software issues and restore the audio functionality. To reboot the iDrive system, follow these steps:
1. Start your car and drive it at a low speed. You need to be in motion for the rebooting to work.
2. Locate the volume dial in the center console and press and hold it for 30 to 45 seconds until the screen goes black.
3. Release the volume dial and wait for one to two minutes for the system to reboot itself.
4. Press the volume dial again to turn on the system and check if the audio is working.
What to Do If the Problem Persists?
If resetting the iDrive system does not solve the problem, you may need to contact your car dealer or a professional mechanic for further assistance.
There may be a hardware issue with the iDrive head unit or the wiring that connects it to the audio sources. You may need to replace or repair these components to fix the error.
Alternatively, you can try disconnecting and reconnecting the battery of your car. This will reset all the electronic systems in your car, including the iDrive system.
However, this may also erase some of your settings and preferences, such as your clock and radio preset. To disconnect and reconnect the battery, follow these steps:
1. Locate the battery in your car’s trunk or under the hood.
2. Use a wrench to loosen and remove the negative cable from the battery terminal.
3. Wait for five to 10 minutes for all the systems to reset.
4. Reattach the negative cable to the battery terminal and tighten it with a wrench.
5. Start your car and check if the audio is working.
Conclusion
The “No Source Available” error in BMW cars is a common problem that affects many owners. It means that your audio system is not receiving any sound from any source.
You can fix this problem by resetting your iDrive system or disconnecting and reconnecting your battery.
