well tonight I got lost somewhere and I needed to turn around on a very narrow road.. long story short, I have dark tinted windows and dark tinted tails.. so I cant see anything when backing up.. I needed to stick my head out the window, open my door, and make a 3000 point turn.. I really need a back up camera.. I have no issue with switching to aux to use it.. I can just plug it strait into the rca in the arm rest.. my question is does that even work when in reverse or only in park? I don't want oem because my lip is painted and I don't want to re do it.. What should I get.. I was thinking a license plate one would do.. simple and clean is what I want.. I have a 2007 g35x sedan.. Thanks!!!
