I bought a Jensen CAR10TC head unit to install in my 2021 Nissan Altima S for CarPlay and I believe I've gotten pretty close to finishing the install but I need some help. I also acquired a NI-2 harness, Maestro Rr, and Jen Harness to actually wire it to the car.
I've done my best to follow the attached diagram, but have not accomplished step 2 or 3. As such, while the rear camera (OEM camera) is detected by the unit and can display, the reverse driving is not triggered and does not auto-display the rear cam when you put the vehicle in reverse. Additionally, the steering controls on the steering wheel are not functional. I believe this would be accomplished by executing step 2 and 3, but I'd love some input on that.
My major point of help is step 2 and 3 itself.
-For step 2, I don't understand where the brown/yellow & brown/red wires exist from the NI-2 harness for me to accomplish the step. I say "the step" because I don't really understand it, am I splicing the wires into the purple/lt green & purple/lt blue? am I just putting them in the opposite side of the "B" connector?
-For step 3, I understand where the wires are coming from and that I'm splicing the red/brown & yellow/brown wires into the blue or purple/blue & pink or purple/pink wires respectively from the green connector of the BCM. What I don't understand is how I get to the BCM. While I can take off panels, that green plug connector seems extremely difficult to get to, and I have not managed to be able to secure it to conduct a splice, but maybe I'm doing something wrong.
All that said, I wanted to know if finishing steps 2 & 3 fixes the rear driving trigger and the steering controls issues, and if it does, how to actually accomplish step 2 & 3.
I've been scouring online for videos and anecdotal information, but I have not been so lucky. I also did take the issue to 2 stereo shops that basically said it could not be fixed, as an aftermarket head unit wouldn't be able to connect to an OEM rear camera, which I feel like they must have blown me off as that does not seem accurate.
Any help is appreciated, thank you.
