How to solve the problem of no sound on the UGODE BMW Android screen.

Some customers who purchased the UGODE BMW Android screen, which includes wireless CarPlay and Android ATUO functionality, found that there was no sound after installation.

The lack of sound on the Android screen is generally caused by installation and settings issues.

1. Check if the original CD player is working properly. Press the “FM/AM” button on the original CD player to see if you can hear the radio.

 If there’s no sound from the radio either, the fiber optic cable might not be properly connected to the male connector on the Android cable. You’ll need to switch the fiber optic cable.   Click for details.

 2. Some BMW cars require connection to the AUX port to output sound

Aux has two switching modes, manual and automatic.
Some models not support Automatically switch AUX and need to be set to manual mode.
