;1631191']Here's part of the wiring diagram for the 2007 Tribeca. Maybe you can figure out which wire is hot (and why it would be shielded).

Hot should be WL and YR

 

 

OK now we are talking....getting alot closer.....when you say WL and YR should be hot this doesnt quite make sense....why would there be (2) 12v sources running....but i havent had time to look at these diagrams closer to see if there is a purpose there may very well be one

If two color codes are shown (e.g. YL), then the second one indicates the color of a stripe on the wire.

 

 

 

Thank you for the color code but i need to know what these wires actually do not just what color they are. Do you have any of those references (12v power, ground, video shield, video hot, etc.).....u have been a big help so far just need to go a bit farther for me to get this thing done... I'll post up pics and a install letter for your help. THANKS!

is there a guide or walk-through of how to play dvd videos using the factory navi monitor? I searched and it brought me here, but i mostly see discussion about back up cameras and other stuff.

 

 

 

it is stated probably three times in this thread you just have to read.....i know its alot but i read all 20 pages

O and one more other thing. Do you have a picture of the connector for the camera itself with labels as shown on these one line diagrams?

See i didnt know there was a control unit (dealer keeps telling me you order the camera and it comes with the cable to plug in the NAV unit im like uhhhh nooo that part number is just for the camera and the 3 inch cable with a connector, Im trying to find the pinout of the connector to wire it up since they obviously wont sell me the cable)....Does someone have a pic of the actual control unit and maybe an oem part number. Im an electrical engineer by trade I can figure this out with some help....

 

 

Did anyone come up with any of this yet?

I'm not exactly sure. That diagram isn't very detailed. If someone could get the labels off the two fuses, that might be helpful.

 

It doesn't have to be two 12 volt sources. One is probably 5v or 3.3v.

ok i just read through the whole thread. So if i buy a cheapo aftermarket dvd player and put it under the passenger seat, and hook it up this way it should work right?

 

rca video output on aftermarket dvd player - > yellow rca input on back of touchscreen

 

3.5mm audio output on aftermarket dvd player - > audiojack input inside armrest

 

Then press info button to toggle sources on touchscreen? And press AUX on factory audio system.

 

And i need to ground the gray wire in back of harness, which acts like grounding the parking brake ?

 

Should work right?

So this should work right ?

 

To get dvd video on factory touchscreen

 

RCA video output on aftermarket dvd player --> yellow rca input on back of touchscreen

 

3.5mm audio output on aftermarket dvd player --> audiojack aux input in armrest.

 

Press info on touch screen and AUX on radio for video/audio.

 

 

Is that it ?

 

Are u guys using an aftermarket dvd player or the factory one without the nav disc in it?

depending on the year leggy u have yes u can use the audio in the armrest only some of us have that jack and yes this is an aftermarket dvd p[layer u cant use the nav one and no thats not it because u need to ground a wire on the screen to watch the movies while driving see the older pages for further directions

"I am in the process of adding a backup camera to my 2008 Outback so that

it works with both the Backup and Aux. inputs on the dashboard monitor. I

am about 2 weeks away from having the time to complete this modification."

 

I have completed this installation. Attached is a photo showing where I have

placed the video distribution amplifier and related circuitry. The white box on

the right is the (modified) video distribution amplifier and the pale blue box in

the center is the switch that selects when the backup camera and the video

distribution amplifier are powered on.

 

When the switch is in the forward position the camera and video distribution

amp are powered on when the vehicle key is in the accessory or run modes,

and when the switch is in the rear position the camera and video distribution

amplifier are powered on whenever the vehicle key is in the accessory or run

modes and the shift lever is in reverse.

 

When the vehicle is in reverse the NAV display automatically switches to the

backup camera, and when the vehicle is in a forward gear pushing the "Info"

button a couple of times will switch to the backup camera.

 

I modified the video distribution amplifier to both improve the design (it is a

typical "consumer grade" product) and also reduce the power consumption

since it is in a somewhat enclosed space. Right now it only consumes 1.2

Watts, which I consider very safe for the nearly enclosed location.

 

All of the new wiring has connectors so that the center console can easily be

removed without cutting any wires. The "all time" power comes from the plug

in outlet power and the "reverse only" power comes from the navigation DVD

player under the driver's seat (the navigation DVD player has the reverse light

power in its wiring harness).

 

The navigation system and its display have also been modified so that they

have full functionality when the vehicle is moving. Note that the previous

modification explanations given by some people are really not quite correct

with regards to the navigation display backup camera connection.

Great job A.Spider but a question for you from a newb...

 

I have only read a bit of this so I understand I may have missed the obvious but...why is this necessary?

 

Aren't the back up vid. input and Aux. vid inputs separate? The back up works in reverse if it detects an input (camera). Otherwise, you would simply play your dvd, tap info twice and watch your DVD?

 

What part of this equation am I missing?

My goal was to be able to use the backup camera in both reverse and

any forward gear. I have no interest in using a DVD player with the NAV

display, although my solution certainly does not prevent that particular

usage.

 

Since the NAV display automatically switches to the 4 pin Molex connector

for a video source when the transmission is in reverse, that connector must

be used to retain the automatic camera switching function. However, that

same connector can't be used when the vehicle not in reverse because it is

internally disconnected whenever the transmission is not in reverse.

 

If backup camera viewing is desired when the transmission is not in reverse

then the AUX input must be used and the INFO button must be pushed twice

to select the NAV display RCA connector as a video source.

 

Hence, the camera must drive both NAV display inputs for complete usage as

described above. Since both NAV display inputs are properly terminated with

75 ohms, 75 ohm output impedance cameras can't drive both inputs without

halving the output signal amplitude. Hence the requirement for using a video

distribution amplifier.

 

I installed the blue box switch to alter the camera mode from only working in

reverse to working all of the time since this was effectively an experimental

setup. Having the camera work all of the time would obviously accomplish my

intended goals, but I was unsure about the power dissipation in an enclosed

space problem (this was before I reduced the power of the video distribution

amplifier, it used to consume considerably more power than it does now).

 

If your goal is to only use a backup camera while in reverse then no video

distribution amplifier is required. Likewise, if you would be willing to always

push the INFO button twice to use the backup camera even while in reverse

then the RCA jack on the back of the NAV display can always be used for a

backup camera and no video distribution amplifier is required. If you want to

use the RCA jack for a DVD player then a backup camera could only be used

with the 4 pin Molex connector, unless you would be willing to install a video

switch.

 

By using a video distribution amplifier in the console box I can use a backup

camera in the automatic reverse mode as well as while not in reverse along

with pushing the INFO button twice. I can also easily unplug the camera from

the video distribution amplifier and plug in a DVD player to get that to show

up on the NAV display (however, I do not have any interest in doing this).

 

Note that the advice being given about which pins on the Molex connector

are for video input and grounding are in fact incorrect. The video should be

applied to pins #1 and #2, with the latter being the shield. Pins #2 and #4

should be tied together and none of the pins should be grounded.

 

Grounding either the camera end of the shield or a pin in the Molex connector

would risk injecting ground noise into the video path since automotive grounds

are anything but "clean" (I was an HDTV engineer many years ago). By using

the connection that I described you will get the cleanest possible video signal.

I to am very interested in the camera you chose. I'm interested in the highest quality picture in the smallest formfactor and do not have enough experience to compare one to another.

 

Oh, and thanks a bunch for the clarification!

don't expect 1080p or anything from the cameras....ur screen resolution isnt even that high...

Virtually any small form factor NTSC black and white or color camera would work

for a backup camera. The picture quality is basically limited by the NAV display,

unless you are trying to use a really bad camera. The camera must have a 75

ohm output impedance (this is standard for video cameras) and be capable of

providing 1V PP of video signal into a 75 ohm load (again, this is standard for

video cameras).

 

I used the "CRIMESTOPPER SV-6300 SECUREVIEW OEM WATERPROOF TRUNK

CAMERA". Note that this is available for under $100 at many places and it can

display a reversed image as a backup camera or a non-reversed image for use

in forward vision by changing a jumper. The field of view is excellent.

 

Also, many of the photos shown for this camera are incorrect, the camera actually

looks like the attached image. It fits perfectly under the ledge across the center

of the Outback tailgate. It also has IR LEDs that automatically come on in very

low light level conditions so it works in total darkness. This feature is generally

not useful unless your backup lights have failed. I did not get it for that feature,

it just came that way. When using IR illumination the image on the NAV display

will be in black and white, since only one "color" is visible.

a.spider,

 

Sorry for all the questions, but might you have a few installed pics to share? Maybe of the Nav. showing the cam. picture?

 

f85Stealth, I understand. The very first thing I noticed about the Nav when I bought the car was how low res it was. Our LR3's display has a much higher resolution. It would be nice if there was an upgrade for it.

I am trying to find out if anyone knows the OEM for the factory installed HDD NAvi units that are on the JDM cars?

I am looking to hack mine to english menus (from the oroginal Japanese) and load the proper local maps (Jamaica) onto it.

 

Any help with a model numbers, etc, OS fo the unit would be helpful.

 

The car does not have a DVD unit, but a 30gb HDD behind the glove box attached to a head unit, much like the 2008 USDM models. You can PM me or just reply to the tread. Cheers:spin:
