No audio devices found
If the 'No audio device found' message is displayed for more than 10 seconds, then your MFD
cannot connect to your Entertainment system. Ensure network and power connections to your
Entertainment system and MFD are correct and free from damage and then power cycle your
system. If the Entertainment system is still not displayed then refer to your equipment's installation
documentation for further troubleshooting information.
