I think I found a way to go about doing this from a "custom" approach. I should note that all of this was found via the
Forrest River Owners Guide --> Component Manuals --> Backup Camera. So big props to Brian and Team for that. I have found that app very useful.
Ok, from my research it appears that all 4 inputs in the system have a
Trigger Wire. The wire is used to send a signal to the system and put that input on the screen until the trigger is satisfied. Its very likely that the reverse camera input trigger wire was used during installation at Dynamax and the OPs problem is the desire to change the view when in reverse. One of the
Custom things I am going to try is looking to see how accessible the trigger wires are. Theoretically you could intercept each trigger wire and make your own set of toggle switches so that you could manually force/trigger the input you want to have full screen. This might be more handy than pressing the same button over and over again to change inputs as I think it is now. Rather, you could easily select which camera you wanted to see quickly.
It appears that there are Trigger Delays that can be set where the system will default back to its normal function after a given time period. If you wanted to use Momentary Buttons for triggers this would come in handy for viewing the camera you want to see at full screen, and then the system reverting back. You can select between 0-15 seconds. .
BUT WAIT, THERES MORE!!!!
It also appears that there are
Reversing Options and
Reversing Priority. This part I am fully theorizing because I am not sure what these do and am curious if they are matching Default Settings or something that was changed during install. The reversing Priority is also interesting as to what it does. All might be things that change what is happening when reversing though.

AHD OSD Display looks to be where you can choose which 4 cam default view you want, or possible to make it 1 Position by default instead of 4 views at once. Not sure though and need to play around.
Have some experimenting to do!
