2009 Tacoma back up camera rear view mirror display

Since you now found that the wiring is in place, you can do as Bret has stated. It be a larger investment, but a better view. There's mating connector to the one you found that can be used to divert the camera signal to a new head unit.

 

I8 also has Fused Battery & Fused Ignition source, ground that can be re-purposed for other features: Dash Cam, Mirror with Compass/Garage Door opener type, etc.

 

Guess i’m a year late, I have a similar situation, i have the cable and it’s up i’m the headliner, how would i go about wiring it to a new head unit, i understand needing a converter, but physically where should i run the cable to get it to the head unit, any info is helpful thank you so much.

EDIT also wondering what head unit would be easily compatible

 

I was mainly after a backup camera and went with this https://www.crutchfield.com/p_104BV765BL/BOSS-Audio-Elite-BV765BLC.html?fr=1&b=BestValue

To me it sounds better than stock and has Bluetooth plus other stuff.

 

And that will plug right into the camera wire that’s in the headliner? or will i still need an adapter

 

The one I installed has an RCA plug input. Comes with a license plate cam with long enough wire for a Taco. RCA is a better connection for video, but automotive likes square plugs with lots of pins

I think it’s unlikely the stock wiring uses an RCA connection. But you could look.

Backup cam is awesome:
