'19 Trailer Camera and on Board Reverse Camera

[Gecko50]

Ok this is for the 2019 new towing camera system WITH optional trailer camera installed. My question is when your trailer is installed and the rear optional hard wired GM camera is installed. When your looking at the trailer camera and stop, you select reverse will the tail gate camera overide you display with a view of the front trailer / tail gate views, OR does the rear heard wired trailer view remain on the display screen? The reason I ask is when you have multiple pull up and reverse activity (yes with a 48 foot trailer GN it happens in traffic with 18 inches clearence on each side) the repeat push toggle screen buttons take up a lot of time for screen switching while in traffic! I have the GM 4 camera system in my '16 Denali. Installed by a GM dealer recommended approved camera dealer.

 

Also is there extension RCA camera cables available? 28 feet just wont make it. 

 

Thanks
