    Headunit to controll a computer?

    I have a new Pioneer MP3 headunit DEH-8600.

    I also have a Pioneer 6 Disk Changer.

    When using the changer the head unit controlls the changer, displays CD-Text, allows you to step forward tracks by scrolling through the track names etc.

    What I dont understand is why hasn't anyone tried to connect a PC to the head unit. While I dont have any idea on where to begin, if a changer can be controlled and track info can be displayed on the headunit, should it be possible to do something similar with a PC connected to the head unit???

    Anyone ever tried this, read about it etc???

    Or am i dreaming?

    most of the time, a carputer is setup to replace a headunit/cdchanger configuration.

    yes it could be done, but why?

    First you'd need to determine the type of connection (serial or parallel, although it's likely a serial conenction) the HU has to the CD Changer. Also, you would need to know the transmission parameters (speed, data bits, etc.)
    You would need to determine what signals the HU is sending to the changer and interpret those signals.
    Then you'd need to write software to send those functions through the port.

    Could it be done? Sure.
    Is it worth it when you can have 600 CDs worth of ripped music (CD-qualiuty or better!) at your fingertipswith just the computer? I don't think so.
    Have you looked in the FAQ yet?
    How about the Wiki?

    Has been done with Alpine M-BUS. Check out the input forum. I think he is also port to Pioneer BUS as well, but not sure.

    I'll agree with the why statement/question.....IMO that goes against what is the essence of having a computer in your car....

    but there are some people who think that they just simply wont survive without a head unit in their car!

    Its what I would term as being:

    A WOLF IN SHEEPS CLOTHING!

    I like the stealth installation and features a head unit offers.

    I just think it should be possible to have the best of both worlds!!!

    How about this for a reason. I am sick of having no radio during the times when my carputer is screwing up or I attempted a software upgrade for my frontend and it hosed the whole thing. I went straight to headless over a year ago and just switched back and added an Alpine HU into my mix. I am much happier. If I could use the HU to interface my PC then even better as I could use the basic controls like FF/RW and forward to next track easily.

    If you search, you will find several discussions. It's been done with most brands. But it's a lot of work, too advanced for me. I also don't see the point. Why waste a DIN? Show me a deck with amplification and signal processing equal to that of a good soundcard and amp. I suppose it could be useful if you listen to the radio a lot though, but that's it.

    I will be selling my Kenwood deck and CD changer once my pc is installed. I can't wait to get rid of it.

    Kenwood example.

    I don't see the point of controlling the computer with the HU when you can use the remote (the one for the HU) to control the computer.
    I can actually go HU Less in my Supra setup but I prefer not to cuz there are time I just have to have AM for traffic report, news and stuff.
    BTW, I can't remember when was the last time I touch one of those button on the HU.
