    Possible to adapt laptop to 3.5mm ?

    My car has a 3.5mm video input on it. It also has usb hookup, but I havent been able to get that to do anything with a usb/usb cable.

    Is there a way to convert usb to 3.5mm video? I'd like to make a cable myself, but I cant find a schematic to make one. Anyone have any tips?

    What vehicle (Year, Make, and Model), what navigation system, and what kind of inputs does it support (As according to your dealer)?

    "3.5mm video input" means nothing, and is not really of any help. What you need to find out, is what kind of video input does it support, and go from there.

    He asked the same question over at the CF forum. Here's what I know so far:

    He has a 2012 Hyundai that has a head unit with USB (most likely for mp3/iPod/iPhone) and a 3.5mm a/v input.
    He has a Pavilion dv6 laptop.

    Honestly dont know what kind of video input it supports. The system is running on Windows CE, with a shell program. Car is a Hyundai Veloster.

    I know it will play other things through the 3.5mm. Xbox works, but I know thats not the same as a computer.

    Excellent info.
    Maybe the capacitor (1F) could help buffer the signal? Probably more useful than its current - I mean, voltage application.



    Trey - I think your are trying to match incompatible systems - a bit like converting a monitor headphone output to carry video (though that's often easy) - or rather, converting it to a video input....
    And if it involves video signal conversion (RGB to composite or HDMI or CYM etc), then IMO forget it - it's cheaper else better changing equipment - though some adapters are an economic option.

    Am I the only one that never understands anything that OldSpark says?
    Probably very knowledgeable but for someone like me, i need a translator lol..

    Sounds good, I'll look for another solution.

    I thought I had seen where someone tied in to the stock display for their carpc. maybe I was wrong.

    The head unit has a 3.5mm video and audio input, much like the cables included with video cameras and portable dvd players. It is very easy to convert analog video to composite, and then connect that to a cable that has composite and two channel rca cables that terminates into a 3.5mm plug (which is included with that particular head unit, apparently). The video quality will most likely suck, but it is possible to achieve what the OP wants.

    Thank-You kegobeer!!

    No - I think you are in fine company, and by far the majority!

    The capacitor bit was me being ridiculous - much as caps for audio systems are ridiculous, and (IMO) extremely amusing (with some exceptions - I'm talking about "the norm").

    I thought the rest was ok though - I just thought of whatever video TLAs etc I could think of (TLAs being Three Letter Acronyms - a subset of MLAs or Multi Letter Acronyms), and my vague recollection of the lack of cheap video converters else their compromised quality. (Though converters now have the possibility of being quality and cheap.)


    BTW - if ever I confustigate you, please ask for clarification if you are interested.
    If it's my jargon or Aussie slang etc, that is usually easy to fix.
    But as to technical complexity, I only too well understand! Especially the simple misunderstandings that underpin much stuff (like caps for amps; battery & charging system behavior; etc) - often so simple in hindsight , but tricky as all hell until YOU get to see the big picture. (And as I suggest, hence easy to get things so wrong or expensive due to some simple misunderstanding or miss - not that I do that, well... not since Thursday anyhow.)
    FYI "confustigate" comes from an old "good-boy's" curse: "Confustigate the muddy bucket of pitch". (To me it sounds like "confuse", though I only know what the last words translate to!) Alas I liked that curse - you can't be told off for foul language. (Much the same as when people tell me "You can't!!" and I reply "DON'T call me a can't!!". That should work in American English too.)


    Apologies for another longie, but I hope the extra stuff was worthwhile.

    Would now be a good time to point out that Sledge is an Aussie
    I too was wondering where on earth you were pulling the capacitor from..

    I don't think it is impossible but yes it sounds like an analogue signal as mentioned used by many cameras. The tricky part will be figuring out what sort of analogue signal and getting the computer to output the same thing.
