    Awesome!! Glad to hear you got the video working! Is it as close to 100% as they way you wanted it to be? Still working on the audio though, right? I know a bit about computers and very little about coding... but unfortunately I don't think I can benefit what you're trying to do with my knowledge. That's a whole different ballpark than where my experience is (which is mainly web programming).

    As far as this interface board, what exactly is that? Do you mean some sort of module that will plug in between the carputer and the Kenwood unit to make the audio/video work (without splicing wires)? I'm not even sure exactly what an interface board is lol. If you could, get us some pictures of your connections and everything and if I see what you have and what you need I will be more than willing to do some research to help you in any way that I can with getting together what you need.

    Thanks for the updates!!

    I REALLY can't wait. To me, this is the holy grail. There is another guy on the boards that just posted an IS300 install. Check out the pics of his screen. His friend built a device that interfaces with the OEM Nav screen. His pics of a PC file listing look pretty sharp to me.

    Thx for the update...

    first off you need to know that the kenwood sirius and cd changer cables are both audio buss cables and they are the same cable but are different from the nav cable they all have the same 13 pin din plug on them if you plug an audio buss cable in to the nav port you could fry your radio the audio buss cable is a navy blue color and the nav cable is a dark red color you need a nav cable for a KNA-DV4100 nav unit there about $60 I think kenwood calls it a AMS cable don't quote me on that
    Thanks for the info. I'll have to do more searching for the nav unit (KNA-DV4100) for the proper cable...

    Heheh. "see if I can fry it".. interesting mindset :-) Better you than me :-O

    If this all works out, I'm planning on using the XBOX Media Center (http://www.xboxmediacenter.de). I really only intend to use it for MP3 playing, but having the other capabilities in there may be nice on occasion. I'll be able to control XBMC completely from one of those mini-USB keyboards for sale in the MP3Car store. I'll probably also write a few XBMC Python scripts to make music selection easier...

    I'm going to try using one of the following RGB solutions to get video out of my XBOX:

    A XBOX RGB adapter
    - http://www.x2vga.com/
    - I've got one of these already so I'll try it first

    XBOX HiDef component video -> RGsB/RGBS/RGBHV converter
    - http://digitalconnection.com/Products/Video/9a65.asp
    - Another forum user, Tranman, mentioned this box in another thread

    So it looks like I'll be sending RGBS video at 480p type resolutions (720x480). Hopefully the Kenwood will accept this.

    On another topic, have you tried sending any audio into the Kenwood through the nav cable? I actually have a factory nav system and if I can send its audio directly to the Kenwood that would rock.

    If you are still having problems attaching/uploading files to the forum, I'd be glad to host documents/pics related to the Kenwood... Just let me know.

    Thanks again for sharing your experiences with this unit.

    Take care,
    Arion

    ya when it is my stuff I don't really care if I screw it up when it is not my unit I am a lot more carefull with it

    the audio authority converter is not the one you need for a Kenwood screen the RGBS output on the converter you found is Scart RGB output Scart uses a composite sync you need a normal sync signal you may have to use 2 converters

    I figured it out you can't post a file bigger than 200K here so if you want to know how to hook a PC up to your Kenwood Nav RGB input and see some screen shots

    Email me at [email protected] and put (Kenwood RGB) in the subject line I will reply with the file it is a .doc file and is 6MB

    Hmmm. What do you mean by "normal sync"? I guess I'm not totally versed in all of the various RGB standards. From what I understand, there is:

    RGsB - RGB, with sync on green (both horizontal/vertical combined)
    RGBS - RGB with separate sync (both horizontal/vertical combined)
    RGBHV - RGB with separate horizontal and vertical sync

    From what I've read, in RGBS the sync can be 'composite' or 'combined' -- a difference based on voltage?

    For separate horizontal and vertical syncs, each sync has its own frequency (represented in Hz?).

    I understand that the frequency range can vary widely based on source and I'm guessing one of the primary problems with trying to get RGB sorted out properly is sync rates and frequencies? With VGA-like frequency ranges being much different than consumer video type devices?

    Given all of this, what type of RGB input does the Kenwood display expect? I sure hope I can get a nice image out of my XBOX into it...

    BTW, to answer some earlier XBOX questions you had, there are some primitive web browsers for the XBOX... There is one that looks promising called LinkxBox and they are working on integrating it into XBMC. Also, the audio playing engine in XBMC has really improved a lot in the last year. There is a nice music library built in where you can search/play music by various criteria. Also, id3 album art is supported, and they added some great music visualizers earlier this year -- integrated Winamp's Milkdrop into XBMC.

    Take care,
    Arion

    Thank's for the xbox info I gota check it out


    the Kenwood needs a +/- mixed sync at TTL level TTL level is 5v peak to peak

    RGBs and RGBS are different standards but offten get confused RGBs is Scart RGB and it uses a combined sync it is a composite video signal and a normal sync frequency signal combined I think the voltage is around 7v but don't quote me on the 7 volts I am not really sure

    RGBS sync is horizontal and vertical sync mixed at TTL level or 5v peak to peak

    RGsB is sync on green it's the same sync signal as RGBS but the sync is mixed in the Green signal

    the Kenwood displays need RGBS +/- TTL Level sync at 1Khz the input is a CGA input is a very old computer video standard invented by IBM back when they made computers now they only sell them it was the first color computer video standard

    Keep me posted about what converter you find and where that will work with your Xbox as more info becomes available about hooking up to a Kenwood I am going to keep adding it to my tutorial

    Are you sure the Audio Authority converter I linked to won't work? I checked out the manual online and it says that it will do "RGBS, composite negative TTL sync on H output pins"...

    Here's a link to the PDF of the manual:
    http://www.digitalconnection.com/dow...9A65manual.pdf

    So in the end were you able to display 720x480 video to the Kenwood display? What adapter setup are you using for VGA/PC hookup?

    BTW, I sent ya an email request for the pics/.doc file you put together... any updates on that? I'll host the files on my web server and any other info we uncover if that'll help others in the future....

    Thanks again for the info on the Kenwood. I'm trying to figure out as much as I can about a possible XBOX hookup before I shell out the $$$ for a Kenwood (and probably more $$$ for some type of RGB adapter)...

    Decoding these proprietary systems is always kinda like solving a puzzle, eh? hehe

    Take care,
    Arion
