Factory Back up camera

Thanks for the reassuring comments. Next week I will know if all that Japanese yen was well spent.

Do you believe your system would work like it should if you had the OEM wiring harness or that box?

Cjanik

yes I think my system would work if I had that box.
Whats happening is the box sends voltage to the NAV when you go in reverse which tells it to switch to rear cam input. when you leave reverse, it tells it to go back. it also does the lines and powers the camera and many other things, but I dont need that as i've got everything to work without it.

ive found 5v goes to pin 40 of the NAV unit (not documented on our 370z but documented on all nissan/infiniti backup camera capable vehicles) but i cant get it to work. might have to trigger something else at the same time that I am unaware of.
