    What about a PC w/ a video card that has TV RCA out? Such as this one.

    I'm assuming this would output a fairly clean picture? But this wouldn't be an option with the Mac mini of course. It would be enough to change my mind and look for a mini PC. Opinions?

    Let me know if I can help you.

    Cheers!!
    your ebay page, some problems.

    under features, your html is a little odd. you have the left column centered with the right column. making it a little hard to know what goes with what. notice "mouse emulator" is next to the middle of the info it goes with, #2 out of 3...

    iMac OS9 is not an OS per say; its a computer model and an older OS no one is going to use in a carputer.

    And you dont list OSX, so is it compatible or not.

    There are UPPD (Universal Pointer Device Driver) (Touch-Based) available and (freely downloadable) for OSX, if the drivers provided happen to not work with your particular application.

    First off, a touch screen is emulating a mouse. This technology isn't propriatary, and has not changed. Assuming that it wouldn't work with OSX, is like stating that OSX (or Windows Vista - if you want to use a different application for arguments sake) is superior to everything on the planet, and sees no need to be able to use the traditional mouse that 300 billion other computer manufacturers and computer users are using right now. That like saying someone designed a car that runs on gas available from a station in egypt only. Sure there is software that would be foreign to all other OS's, but not a mouse. The only reason that I can see that a driver for a mouse not be available, would be that the OS has no consumer usage or need for support.

    I know I'm over explaining a little like that, but I suppose I'm trying to say that the hardware function is common to a computer, period. The driver, since they have been designed to be, and are available as universal drivers, states that you should have no worries with any OS.

    Excellent.. I wasn't too concerned that it wouldn't work, just wanted some re-assurance. Thanks for clearing that up.

    In order to not let this issue die.. I present a new option.

    What about using Apple's DVI -> VGA from the Mac Mini and going into a "PC to TV converter"? Such as this one. I don't know how much feedback I will get on this particular converter, I have a feeling it may be something I just purchase and try on my own. Thanks!

    Nobody says it won't work. It will just output an RCA signal. That's an analog signal with low resolution and fuzzy quality because that is what the monitor will display.

    It has little to do with the quality of the device that converts the signal. Well...okay...it has a little to do with that. The best quality device is called a scan converter. That will give you the highest quality ****ty RCA signal you can get.

    I can understand that you are looking at the stock nav and going, "well, hmmm. It looks pretty bright and crisp. There MUST be some way I can hook up my Mac to that if only the signal gets cleaned up so it will look just as good."

    It won't. It's not like you can't use the Mac, or any other PC on a TV. You can. It just isn't as high a resolution as a VGA monitor. That means you have to make all of the text on the screen much larger so it will be readable. Think 18 point font, here.

    You: Trying to convert the Mac to go from high resolution to low resolution.

    What you should be thinking about: Installing a VGA screen and displaying your Nav system signal on it.

    Going from low res to high res it will look much better. If you get a Xenarc screen, you can switch an RCA output signal into the screen and it will automatically display it on screen for you. Switch it back and you'll get all that VGA goodness for computer use.

    You don't have to believe me or take my advice. It's cheap to experiment and I'm not trying to discourage you from doing it. Either way, though, you have to hack your nav screen to show the Mac picture or hack your nav system to connect to a replacment VGA monitor.

    One last point for consideration. If you go the route of displaying the Mac on the nav screen via an RCA output, don't think it will be useful for impressing your friends. The colors will be slightly washed out and the edges will be fuzzy. They'll notice and think the install looks ghetto.

    Alright, after several weeks of hearing everyone's input, it has finally sunk in. I'm going to move past from trying to get a decent signal using composite input. Unfortunately it was the only adapter I've found to use with my stock screen. But I'm convinced it simply is not worth all the time and money for a ****ty picture. Thanks for all your input, it has definetely not been ignored or taken lightly.

    Now I am not sure what options I have left. I don't wish to replace my factory screen, because I'd like to keep my stock NAV system and more importantly this screen displays my cars climate control information. I don't think I want to tackle trying to transfer this data onto an aftermarket screen. Cutting up my dash isn't very appealing to me either on an 07 car that I still owe 20k on. Oh my options are running thin..
