Terminator, I emailed you!

did you get the file?

yep, thanks!!

So I got the Navtool working, all my connections are made through a constant 12v for the unit since I coudn't find ignition 12v. just temporarily to see if it'll work, I put the car in reverse and the screen keeps flickering. i attached a video below. I'm using a 40A relay if it matters.

where are you picking up your reverse signal for the Navtool from?

i connected the relay to the yellow/white wire from the bottom of the liftgate right next to the plastic cover that goes over the spare tire

yellow/white wire... can you be more specific - what signal is this wire? why did you choose that particular wire?

Its the reverse light wire, no?

the reverse light is a Pulse Modulated Wave signal, __|--|___|--|___|--|___, the signal is going up to full 12V and then drops down to 0V, then goes back up to 12V... This way BMW controls the intensity of the light output. As a result, your relay is flipping back and forth, and in turn, flickers the screen.

I forgot, do you have Park Distance Control?

Nope, I don't have PDC
