The newer radios (AVM70LH) have VIN, LIN and RIN(Video, Left, Right IN), as well as CAM IN. The Camera Audio Input is on a separate harness and connector to the side of the unit with the Bluetooth Antenna. The camera video output from the video switcher is connected into the CAM IN. There is no input to the Camera Audio Input or the Audio-Video inputs.
If you hooked the output of the video switcher into the Audio-Video inputs you would then not be able to listen to the radio while monitoring the rear-camera through the Audio Video function instead of the Rear Camera function.
More than not having any audio, during a turn, the bigger problem I believe, is with the Firmware of the unit. The unit does not go back to the last function it was at(Rear Camera) after it has been triggered by the camera switcher(trigger on the Orange(Reverse (+) wire), instead, it goes to the Radio Function. The Axerra site had no firmware upgrades for the radio and I never bothered to contact them, determined it would be just easier to disconnect the trigger.
Thought about going to a separate monitor/video over a rear view mirror, but I was happy with the rear view camera picture quality on the radio, and have one less monitor. (I run "Torque" on an old tablet, as well as have a separate GPS). The Bluetooth for hands free works fine, so another plus.
Hope Big Brother doesn't find out I made the change!
