Hello, For music I use the IPhone 14 with IOS 16.7 with my own music files on the IPhone. Firmware & App are installed and updated. Devices are turned off and on. I can either listen to music or talk to my partner. If I open the intercom in the app, the music switches off. If I turn on the music, the intercom switches off. I need precise programming instructions so that I can bring the two together or, if available, a video. There is nothing about this in your instruction manual. Except that using both at the same time is possible when Audio Overlay is activated... and that's it. Best regards Willy
