    we have tested a couple units for home and have built a YPbPr interfaces but we had some concerns on parts count and pricing, we also had some concerns with scaling since most of the composite input adapters are meant for I or P formats not for PC standards. are you looking for a RGsB interface or some other solution? if you read the posts above we can also build a interface for the composite side but that would be redundant for the 740BT(or many Alpine H/U's) due to the fact that it's already equipped with a composite input. now when we release the touchscreen controller interface we may also make a option for composite into the screen with the ability of touchscreen control for the composite input this would take care of the the 400X232 alpine monitors but the sacrifice would be composite, the gains will be a integrated H/U with touchscreen control!

    My reason for this is, I want to use my modded xbox. (mostly because of the quick boot/shutdown times, and because XBMC is a great piece of software). The xbox can put out standard def (composite), or hd (component, 480i, 480p, 720p, 1080i). It would be great to be able to use the component.

    The input on the 740bt you're interfacing to, what is it exactly?


    I'm considering developing an interface between a touchscreen (theoretically any touchscreen) and an xbox (or any computer), to be able to truly emulate a mouse (writing drivers for the xbox/xbmc isnt fun from what i hear...)

    We are interfacing with the RGB input to the 740. Also the touchscreen controller will be usb, we are not sure what all it is going to be able to emulate because we are interfacing the data how alpine made it. So we dont know if this will provide full mouse emulation.

    I want component (YPbPr) in. Would it be possible to create a (custom) unit, that has both vga in and YPbPr in?

    I will go back to our notes. I think we were able to get 480 I/P to scale correctly on RGsB. but I remember there being a issue but don't recall what it was. Maybe further down the line as we get the VGA units ready for deployment we will take a look at a componet input.


    etiscc: if you can confirm or correct me on what I recall about the componet input I would appreciate it!

I think they said that it could be interfaced the vehicle hub.
    you are right. i check. only the intelligent HUs can. only thing is i don't need the intelligent ones with amps and the on board DSPs. . Guess 740bt is a very good choice.

    you bloody beauty, this is the one thing that will allow me to finally get a car PC - the cheaper touchscreens put me off a little...

    Anyway would be definitely keen on one of these interfaces as im looking at one of hese units at the moment anyway, although i have a few questions...

    1) im in australia and we have the IVA-W202E which looks very similar to the unit you are testing, and was wondering if the sound processing features (ie. balance, fader, eq etc) would be retained? or would all of these have to be manually done through the windows sound setup? can the standard ALPINE interface still be acessed to make adjustments such as these?

    2) volume buttons - will the volume buttons on the screen work?

    3) will features such as the built in DVD player and AM/FM radio still be able to be used?

    4) amplifier connections - will this still be done via the CarPC soundcard? or will the RCA outputs on the screen be able to be used?

    5) any idea on how much this interface will be available for? approximatley?

    sorry about all the questions haha feel that they will be usefull for all...

    keep up the awsome work!

    Glad to here you like it. Now to your questions. I looked up the unit and found that this is not the unit we are working on. The 202 is comparible to our 205, which is an intergrated h/u. We are currently interfacing a TME-M740BT, which is a stand alone monitor with some other cool features. With that screen you would control your audio system through your pc and amp setup. Our unit should work with other screens but we have not been able to test. We will be sure to keep you posted.

    Yes we are able to get 480i which has a bit of a centering issue. But 480p looked ok, still not up to standards for anything with small text. I think if there is more demand for that input I think we can make that happen.
