This is confusing. You said above that you didn't need the Riesler interface:

Which is true. The radio doesn't need the interface if it doesn't cut out. But Wpoll is correct:

The Android radio can work and the Riesler app will launch- But the app alone cannot tell you anything without a physical interface that is connected into the IBus. You indicate above that you *did* install the USB (Rielser Interface). Xtrons has simplified the connections for Reisler by including a harness for the physical USB. They followed the guys at AVIN who have sought to make the easiest- and therefore the commonly most expensive option for Android radios in the E53.
So I think we're solving two different problems here:
(1) The OP and the thread focus on the Riesler Interface enabling the DSP amp to think there is a radio in the loop. If I may, I think for your install, the radio worked fine without cutting out the audio.
(2) A USB Interface and a physical connection to the bus is absolutely necessary to enable the IBus app to function with communication to the bus.
Your radio worked fine as you say, but the confusion arrived between the function of the radio- which does not necessarily require the USB interface- vs the function of the IBUS app, which does.
