BU camera feed to RV mirror

New poster here. Just bought an 07 DC and working through some transmission issues now. Just found a bad S2 shift solenoid as the culprit . Pan was never off before and those bolts were seized to a level i have rarely seen :-(. STILL trying to get themout!

my 11 tacoma DCLB has a backup camera that displays in the RV mirror and have come to find that very helpful with a long truck. Surprisingly,the tundra is the same length as the taco. The tundra has an aftermarket TG handle with a built in camera and presume it plugs inti the stock harness. PO had a small display stuck on the dash above the radio, but it looks tacky and block the dash display. I planned to add a simple aftermarket stereo but don’t want to spend 100’s more for a display type that could display the camera. Any good ways to get anRV mirror that will display this feed? I am guessing that these a spit out a standard video signal of some sort. I really like having the camera displayed in the RV mirror.

thanks in advance.
