OEM Navigation Hood Retrofit for Carputer Application
Goal: To install the OEM Navigation hood into a car that did not come with the Nav option, and maintain the motorized “Open” and “Tilt” flip-up functions.
Background: A lot of us are beginning to get into carputer builds for our cars. Most of us want to maintain that OEM look and feel and decided one of the better options is to house our carputer screen in the OEM navigation hood. For owners whose car came with the factory nav option, it’s almost as simple as replacing the stock LCD display with a higher resolution, touch screen display, with no issues retaining the Open/Tilt function. However, for those cars that did not come with the nav option, it becomes a little tougher. Up until this point, people either leave buttons non-functional and manually flip up the screens, one person managed to build a circuit board to control the functions (see following link), or give up all together.

So my first disclaimer is that I’m not a car electronic guru. I’m hoping that between all the engineers, and experts on this forum, we can find a solution to probably a simple problem. Maybe as simple as tap here for POWER, here for ACC, and here for GROUND.
Here is a picture of the on-board PCB, which is located on the back of the OEM nav LCD. I believe these PCBs control the motor that opens/tilt the hood, as well as feeding the video signals to the LCD:
Nav wire harness (24 pin – 2 rows; 6 pin – 1 row):
Here are the diagrams from the electrical manual:

my own excitement i believe i thought it was sent two weeks ago it was sent last friday. stupid anxiety so excited to get this thing going only to run into a brick wall w/ the hood lol. i also need to get my hd radio cable in. sinec he just got stock a few days ago i'm going to be a bit frustrated if i get it before the hood :D usps better not be slow. i wanted to get a full weekend of attempts in w/ the hood this weekend, unless it shows up tomorrowit doesn't look like that will happen.

I ran into this same problem when I had my hood and just gave up on it. It became too much of a headache to get everything figured out and the hood and screen was just sitting around waiting to be installed and I was getting frustrated..so I sold both and got the MS front bumper instead!
Best of luck to you guys! Its a total bitch!!

I've tested every pin with a multimeter, and with my very limited knowledge and after some sparks flying, doesn't look like I can find and isolate the correct signal to power the unit and control the hood.
I am in the process of building the circuit from rprzybyl in this thread . I'm at a point where I need to figure out which pin on the relay hooks up to the wires coming out of the servo/motor.

i also did the same ra can you post the pix of your circuit both top and bottom when you finish? i have had problems w/ my relay. aka power goes in switch works no power comes out doesn't matter if it is switched or not. even wired according to the back of the box as best i can tell i didn't find one that is the exact same as the wireing doc though and got one from radio shack w/ the same power numbers
