I had a 2017 Chateau, and it muted the stereo when I used the turn signals unless I selected the rear view camera mode, so I normally drove with the rear camera display on.
I have a new 2018 Chateau with a different model Axxera, and even after selecting the rear camera mode it mutes when I use a turn signal, and then it switches out of the rear view camera mode. So they took an annoying feature and managed to make it even more annoying.
I head that there is an orange wire, which is the camera input signal. If you cut this wire it will no longer mute your stereo and switch modes when you use a turn signal, but it also won't automatically display the rear camera when you go into reverse. I may cut this wire since it's not a big deal to select the rear camera display when you need it.
