    BTW flip flops will not work cause the RGB color data is still sent out at 31kHz and your vertical sync will be out of sync

    Well, I've tried using PStrip, but i didn't get closer to seeing my desktop twice on the screen.

    Can you exlpain better your question ?

    Yes .... it's automatic when you switches back, for instance it goes to gps or cd player or even radio ...

    to have this possibility you must disconect the "gala" system ... it get the velocity and cut of the image when you are driving ....

    I don't think I need to explain furthermore, because you just answered it. I had a clue it had something to do with the SCALA signal. I just wondered. thanks for the reply!

    Needs,

    Nice job finding the converter! Unfortunately, I don't think it'll work with my system. The connectors are way different, and I am thinking that it wouldn't work anyway.

    The thing is, the readings I am getting on the OEM video signal just don't match up with a digital signal. I could be wrong, but I really don't think it seems correct.

    In any case, good luck with your interfaces guys! I am still working on mine.

    Hey, don't think that another shape of connector means your stuff is incompatible, because I'm pretty confident in this thing. Although I'm not gonna get it (for the moment) because I already have my CarTFT 7" TS for a month and I'm working on my software and my case.

    I'll post a picture in a couple of days showing you that having an OEM-connector does not mean that you can 't use it. (In my car I have a 12-pin mini-din connector at the back of my OEM GPS/audio/screen-system. This is custom, a 10 pin mini-din connector is pretty hard to find. (Although they have it in the store that also sells the converter in previous post) I'm not gonna buy it there because I already have created my own 'custom' connector for it. It's very cheap and it works fine.

    Needs,

    I don't doubt that it will conceptually work with my application, but the thing is, I don't think that my screen is looking for a digital RGB signal. I'm almost positive that the signal is analog, and that's why I am having so much trouble with it. I could be wrong though...

    I just e-mailed Denso Corp in Australia...hopefully they can help me out or at least point me in the right direction (Denso is the manufacturer of my OEM navigation computer).

    Hi, I haven't read this too closely so I might be reposting something that was already suggested... but there's quite a few aftermarket devices out there that let you tap into the nav system and output different sources into the nav screen.. nav-tv is one of them.. I saw a fairly good one a while back for about $500 US but I forget what it was called... Keep in mind though, I never saw anything about factory touchsreens here, so you might have to check (nav-tv in particular seems to specialize in more high-end vehicles)
    hope that helps.

    On the Touchscreen integration i googled the terms and I got these links:

    This guy has integrated an mp3-cd player into his Toyota Prius Touchscreen:

    More on the controls for the above mod:

    [edit]
    Basically, instead of out-putting the Image to the screen, you can use the OEM CD Changer image, and have the computer output CD-TEXT to the Nav computer. Then analyse the signals the nav system outputs when you press each button (on the touchscreen), and tie those outputs to the computer's parallel port and have the computer react appropriately to each of these signals.

    Hope this helps!
