A question before I get out an o scope has anyone sucessfuly used a kenwood nav RGB input for video?
A kenwood tech support guy told me it is a standard RGB input 600x800 Fv=15khz Fh=60hz
does anyone have any info on the kenwood Nav data buss?
here are some roumors from the same tech guy
the kenwood nav unit hardware is an Industrial PC using standard hardware
( this is not realy a roumor it is fact industry insiders like me have known this for years the Alpine has standard IPC hardware as well and the Pioneer is said to be 60% IPC ) the O.S. he heard is said to be a version of windows ce but he belives it is most likly a version of Linux witch is what I have been told as well
thinkin what I am thinkin
If the hardware is standard pc hardware than maybe we can just plug the data into a USB or SERIAL port and load drivers I say this because it is possable that the data is one way I have not been able think of a reason why the nav would need to send data back to the head unit if the data is one way then why wouldn't kenwood use off the shelf hardware and software
it saves them time and money
what do you think
Kenwood's "RGB" is used for data such as touchscreen and nav controls. The actual video is sent through a composite video cable. A Kenwood NAV unit has an RGB (kinda looks like an S-Video or PS-2 cable) AND a composite video cable sent to the lcd head unit.
bagwellfive your wrong and seem to be uneducated about the standards and hardware you are speeking of
the kenwood nav does have a RGB output and the kenwood monitors also have an RGB input the nav also does have a composite video out for use with a composite monitor if you are trying to save a few bucks
RGB is short for RGBVH witch means red green blue vertical sync and horizontal sync there are many variants of RGB pc VGA is one of them no data or control signals can be sent through an RGB signal
I am posting this thread to see if anyone knows if I can just wire up a custom cable or if I will need a converter to convert from one RGB standard to another I am asking to save time and not have to do a lot of testing to find out
the cable you say kinda looks like an S-Video or PS-2 cable is a custom cable with a standard 13 pin din plug at both ends the cable has wires for RGBVH, analog audio, power up signal, common ground, and control data, and a few extra unused wires
faakoff w/that 'uneducated' bull****.
that 13-pin data din plug has been used for years as for things like CD changers. The only thing that remotely resembles that pinout while carrying video signals was made for old-school Atari's. Having barked up this tree before, I've found several different pinout diagrams that may be relevant.
8. GND (Audio)
13. GND (Video)
1 AO Audio Out
2 CVIDEO Composite Video
3 CS Clock Select
4 MD Monochrome Detect / Clock In
5 AI Audio In
6 G Green
7 R Red
8 +12V +12 VDC (520ST has GND)
9 HSYNC Horizontal Sync
10 B Blue
11 MVIDEO Monochrome Video
12 VSYNC Vertical Sync
13 GND Ground
the most relevant to your application would be the first of two pinout diagrams since the second dwells into proprietary atari functions.
hope this helps.
I got VGA video on a Kenwood DDX 7015
tonight I got a Kenwood nav cable witch I promptly cut up
here's what I learned so far
blue = +5v power up signal
gray = seems to be same as blue
purple = +5v nav turn on signal
orange & pink wires seem to be data they spike to .2 volts DC when the screen is touched I need to do some testing with an O scope to be sure
there are two gray sheilded cables inside the nav cable the small one has 2 wires in side
white = I think is audio left +
red = I think is audio right +
sheild = ground
the bigger shielded cable is the RGB signal cable
yellow = green
white = blue
red = red
green = Fh
shield = ground for all signals
compatable Fh = 60hz only
tested at 640x480 32 bit true color 60hz
there is no vertical sync input wire
the video needs some kind of converter I am getting a double image and it is not centered at all but the small text was quite readable it was a little fuzzy but no more fuzzy than my old 7" VGA screen at 800x600 I think the fuz will go away after a little video scaling
what you guys think
I will mess around with it some more when I have some time
That's tight! I just installed a Pioneer AVIC-88DVD. These nav units are definitely computers. My unit has a RISC processor and 64mb of ram. It even has a PCMCIA slot.
The Pioneer RGB cable is 26pin and when connected to the Pioneer AVD-W6210 has a very sharp picture. The RGB cable carries video, audio and data (touchscreen and button input).
You must have a small pile of cash lying around if you're tearing up your RGB cable. I know for Pioneer's there cables cost $75+,
The DDX7015 is 480x234. Nearly all navigation system screens are like this (except for the new Eclipse Dual DIN AVX units and the Alpine IVA-D910).
I'll be damned if you could get input from a computer to look half-decent...good luck and I want more pics!

that is not true the older screens were the DDX7015's lcd has a native res of 600x800 all newer Kenwood nav screens are 600x800 but I have a feeling that the RGB video controller in it may only go as high as 640x480 I should know for sure in a few days
Alpine has a HD screen comming out in a few months and kenwood will by next august there booth said to be 720p
