The 2011 BMW F10 is equipped with a Chinese Android screen.The sound is broadcasted via all the speakers on the original radio.In contrast, the functionality of the speakers on the Android screen is limited to the right side.Numerous attempts have been made, albeit without success.Perhaps an individual who has had a similar issue can provide assistance.I neglected to clarify that the aux wire is unnecessary for the sound to be produced.
Thank you in advance.

What is the duration of its installation and has it ever been functional?

The connections are located inside the expansive multiconnector, which is attached to the original multiplug located at the rear of the current device. Determining the specific function of each wire is challenging due to the lack of documentation.

Perform the wiggle test on each specimen and ascertain its potential for isolation.

The connections, including the fibre optic cable, were thoroughly examined.All is well.As previously mentioned, the BMW radio emits sound via all of its speakers.However, while transitioning to the Android platform, all functionalities are also there, including Android Auto Carplay and GPS camera. The issue is to the auditory output only emanating from the right-hand speakers of the vehicle.I own the equilibrium. That is not the matter.I am uncertain about the potential alternative explanations.

Hence, I inquired if it had ever been successful. It is possible that the recently installed item is defective. Has the multi connecter been disconnected and reseated?

I appreciate your acknowledgment of a defective device. Initially, I had the intention of returning a first screen that only produced sound on the right side of the speakers.I had the belief that I was encountering a faulty device.Last week, I acquired a new one from a different vendor.However, similar to the first one, the sound is only produced by the right speakers.Therefore, I have determined that the issue does not lie with the android screen.I have thoroughly examined all of my links and have not identified any issues.As mentioned in my previous article, all functions are functioning properly on the Android platform, with the exception of the sound being produced only on the right side. However, when transitioning to the OEM radio, I am able to hear sound from all of the speakers.I neglected to specify that the head unit measures 12.3 inches.

The sound from the Android device is connected to the quadlock via the aux in, instead of using a 3.5mm connector. I have previously encountered a situation in which a wire inside the android loom was inadvertently dislodged from its designated position within the quadlock, resulting in an inability to establish a connection with the loom vehicle side.

Why not explicitly state that you have already returned it? :oops:

You must substantiate or refute the output of the Android. I would use colour codes to identify the speaker outputs from the existing head unit and determine their corresponding wires in the new connection.

The speaker wires appear as a cluster of purple/white wires located on the left side, positioned at the top of the connection block.

Next, establish a temporary link to a speaker and see the content shown on the Android screen. In my opinion, there seems to be a wiring malfunction in the connection.

Expressing all of this may seem peculiar if you had the same defect on two distinct devices.Uncertain:

Has the user examined the Android menu screen to determine the central location of the balancing control?

Is there a tiny 3.5mm jack included inside the system? They have a reputation for being unipedal.

Android devices do not directly output sound to speakers. Instead, the sound is routed via the auxiliary input and then connected to the BMW amplifier. As a result, the speaker output cannot be seen on the Android screen.

Inaccurate alignment.
Do you have a nearby vehicle audio business that they would be immediately familiar with?

It is a thought that had not crossed my mind.I want to trace the speaker wires from the Android connector and ascertain their correspondence with the wires on the original equipment manufacturer (OEM) socket.Concerning the auxiliary cable.The majority of cic models get sound via the auxiliary input.Nevertheless, when connecting the wire to the aux port, an audible humming or static sound was detected.The balance is precisely positioned in the centre.Therefore, that is not the issue.I really value the feedback provided by everyone.The objective is to remove the device and examine the speaker wires from the Android plug to determine their synchronisation with the ones on the BMW connector.
