    the rmx2s/4s is not IR... and in any case, its a interface without the joystick...

    sounds like what uoi want to do, is have he PC emulate a SONY MD/CD changer, and ive come close to that, i just didnt see any point...

    basicly you want unilink to rs232.... with emulation of CD/MD
    some software on the PC would need to be written...
    i prob dont have the time...

    why would you need to write software on the PC? I figured once the interface can send stuf to the pC, then girder could sort out the rest?

    you didn't see any point in controlling the pc with the headunit? for one it's a great input device which looks good and feels good. It;s a great thing to have alongside a touchscreen, if not replacing the touch screen completely. Then there's the headunit display. If you go as far as sending the song title back to the headunit then you will have mroe space on the pc's monitor for everything else like sat nav etc.

    This way, the joystick (either the IR one or the 3.5mm plug one, whichever fits your radio) could again be used to control the PC, but at the same time can be used for the headunit when the source isn't the cd changer.

    Otherwise I'd want two joysticks, one for hte PC and one for the headunit which wil look very unprofessional.

    depening on how much you want the pc to do, there are some responsibilities as a CD/MD changer, that has to be handled....

    no, i didnt see any point in the head unit controlling the pc, unless u wanted to make a huge media changer, make the pc serve mp3s to the sony head unit... and yes we could send track/title info back to the HU....

    if your gonna put a PC in a car, im not sure about the HU...
    i could see a HU with an embedded PC, but hey your talking to someone who doesnt have a PC in the car (and doesnt want one)

    Well I've looked into the schematics and there are loads of people who have simply enabled the cd changed input of the headunit wthi a simple circuit with a PIC. The PIC just emualtes a cd changer so the headunit sees there's something there and enables the AUdio inputs. the code for the PIC is freely available and that handles all teh cd changer's responsibilities.

    This is what I was planning to do, just enable the audio in. But hten I figured if it's possible to go further and acutally control the pc withthe headunit as well it would be better. The reason i don't want to leave out hte headunit is for the cd player (a pc one will jsut add to the cost of hte system) and the radio (the usb ones are nowhere near as good). also if anythign was to happen withthe pc to make it not work i can't be bothered to mess around trying to get windows to work while i'm in my car, so i could jsu play a cd with the headunit.

    Just a little plug to say I bought one of these from Mitch about a week ago. After many dead ends trying to get various IR steering wheel remote to work, this dongle hooked up to a Sony RM-X4s is a godsend.

    Had it setup through Girder in about 5 minutes to control WMP9 on my test system. Definately worth the cost and Mitch had it built and shipped in days (I live in the UK so seeing it a few days later was a pleasant shock!).

    Recommended if you are in the market for a controller like this.
    2000 Vauxhall Vectra SXi
    EPIA M12000 / 256MB RAM
    PW-120 + ITPS
    Slot Loading CDRW/DVD
    30GB 2.5in HD
    Lilliput 7" VGA + Touchscreen
    GPS Nav
    Installation progress {+++++++} (Installed! :) )

    I love my sony remote

    Hello Mitch, do you know if I can connect the "Sony RM-X4S Wired remote control" to the "PAC SWI-X Radio Control" which learns and copies any remote signal for any radio and assigns imputes from controllers, in this case from the Sony rmx4s. So do you have created any device that would do the connection? I would like to control my "Kenwood DPX-301 receiver" with my Sony remote, although this receiver doesn't support a wire remote I can use the PAC SWI-X to transmit signals similar to what the Kenwood remote transmitter transmits to the head unit.

    I am also interested in installing a computer in my car, because I am so attach to them, so I would like to buy one of the pc controllers you have created.

    Question for everyone, does anyone has or ever seen any joysticks made by Saitek? I have a st290pro joystick and it works great to create macros and single key strokes, unfortunately I can’t load the next track, last track, play, pause, stop, volume up and down from my keyboard into the user interface that creates the profiles for this joystick. Does anyone know why?

    I recommend this joy, it has a little hat on top of the joy that can be use as a mouse, and the buttons can be programmed for the same mousi means too (right and left click). If I could take this joy apart and cot it down, to a desirable size and attach it to the car some where next to the steering wheel like the Sony RM-X4S I think that it would be a sweet solution, but it would have to work with the volume up and down, so if I am using the GPS on my car or any other program, I would not have to have a combo of keys strokes to turn the volume up and down, cose this only works if you are on top of the interface, in other words, you will need to have a program like windows media player selected.

    Thanks, Jose

    nothing i make, will do ya

    oddly i prob could make a device that converts the sony rm-x4s to kenwood IR
    but it would be some work, and a new avenue for me, i have decoded IR, never encoded it

    anyway, my rm-x4s interface is for pc's, rm-x4s to rs232 strings
