    First off, Cdr, your isntall has been an inspiration for me to do the same to my '03 E46 325i. It's a kick-*** install.

    I'm most of the way through my "little project" now, but have hit a roadblock. I'm trying to map the steering wheel buttons to MediaCar hotkeys just like you did. I'm no programmer, so I had to pretty much copy and paste your instructions in your "IBUS: How to Connect" post. I changed everything that you said to change and then loaded the IBusComM program and then MediaCar. And the buttons didn't work. I read through all of the commented out lines in the .ini file trying to figure out what I did worng, but it's pretty much greek to me.

    I'm assuming that since we both drive E46's the codes will be the same? If this is the case, can you email me a copy of the .ini file as you have it? If the codes aren't the same, I'll have to go check my logger to see what they are in my car.

    I've attached the .ini file as I have altered it so you can get an idea of what I've tried already. Your reward for helping me will be a good laugh at my expense when you read it.

    Since my question has no response from CDR, I am also interested by the ini file.

    Thanks

    Here is the file. When you've downloaded it you'll have to rename it with a .ini extension like this


    IBusComMa.ini


    Then run the program before opening Mediacar and you should have working buttons.

    YOU TOTALLY RULE!!!! That worked perfectly!

    Thank you so much.

    Now to figure out how to create new keyboard shortcuts within MediaCar (want a shortcut to the magnifying glass button and "Playlist Tray +" buttons, but there aren't any). time, I guess.

    Thanks again.

    Okay, another IBus question for you BMW guys that have been so cool thus far:

    Reading through the ini files for IBusComM, and from information on the HacktheIBus Yahoo group (which is such a mess as to be almost worthless as a resource), it would seem that you can also use the radio buttons (CD 1-6 and fwd/back) as command buttons for the computer. In fact, it looks like IBusComM has them mapped to shortcut keys by default.

    Yet they don't seem to work for me. My initial thought was maybe IBusComM is just using the wrong IBus codes for those buttons. So I used IBusAnalyzer to check and see. And this is where things get weird. It seems that none of the buttons on my Business CD H/U are broadcasting IBus signals at all! When I press a steering wheel button, IBusAnalyzer reads packets and tells me what's going on. When I press the "CD 1" button, though, nothing happens. Not even an unknown packet or anything. Just blank screen. Also, IBusAnalyzer has a little popup window you can use to simulate button presses to the bus. It gives you a generic little GUI with all of your steering wheel and radio buttons and supposedly when you press one, it causes that function to happen on the system. This also doesn't seem to work.

    Is this because there is no CD changer harness plugged into the H/U? That would seem like needlessly complicated electronics for it to detect a device before allowing communication as opposed to just broadcasting everything to the bus no matter what.

    The short version is, I would like to map shortkut keys to the H/U buttons. Is this possible?

    Add a DSSC for turning on the Display...

    If you don't want to see the bootup screens, pop a DSSC in there. It turns on your display (and amps, carputer, etc) when you turn the car on. You can adjust the delay until the display turns on, so you can bypass the entire BIOS display entirely.

    Configure it to turn on the Display when the interface is up, and it will look much more integrated/OEM.

    Mad props on the install, BTW. It's incredible!

    HTH,

    Sorry peeps I never had my reply to post thing enabled so I got no emails.. Thanks to BMWOrangeDesign for sharing my ini file.. he grabbed it from me at the UK Meet. :-) was good day, enjoyed it greatly.

    GeddyT unsure about the mapping off your headunit buttons, are you sure the headunit is compatable with a multi cd unit ? I seemed to remember have probs in my last BMW something to do with if it had RDS wrote on the front, cant quite remember.. I think if it had, then it was.. if it hadnt then it wasnt.

    I'm going on to phase two soon, prob upgrading the hardware a bit, and afew bits and bobs. All in the planning stages at the mo, but should improve the setup 100%

    cheers

    First of all the items listed below are installed at the present time.

    Hardware
    Opus 150w
    Xenarc 700TSV
    Epia M10000 (with custom bios)
    20 Gig 2 1/2 Laptop Drive (going to upgrade when needed)
    512MB DDR
    Mircosoft MN-710 54Mbs Wifi
    16 x DVD Rom (going to upgrade)
    D-Link Radio
    Fortuna Serial GPS
    I-Bus Interface
    Mini USB keyboard
    4 Port USB 2.0 Powered Hub

    Software
    Windows XP Pro
    Mediacar (with custom skins)
    WinDVD
    Destinator 2 (SDK version)
    Tons of MP3's

    First of all when I bought the car it had a Kenwood 920 satnav unit it, so after removing this and selling it on ebay I was ready to start my install.

    The first thing I needed was to find a box to stick a motherboard in. I wanted it to go where the kenwood 10 disc changer went in the boot. After searching everywhere I found a plastic box that fitted just right. I bought it from www.cpc.co.uk for about £17. I then bought a M10000 motherboard. I was thinking of getting the new MII 12000 epia board, but I needed two serial ports and that only had one. After a bit of cutting and chopping I ended up with the epia board, i-bus interface and my harddrive all mounted in the case nice.. O + a blue neon light for good measure. I also mounted a USB port on the side of the case, this is used for attaching a usb pen or harddrive to for exchanging data.



    sadly I couldnt fit the opus in, so thats just stuck to the boot with velcro for now. I dont think I will any problems with heat on the opus as its got quite alot of room there. I then had another hole to fill. I decided to mount a dvd rom as well, this was where the kenwood satnav dvd unit was. I still need to fill the holes in or get a replacement side carpet bit for it.. you will see what I mean later.



    Thats the boot stuff done. I took 5v rail from the opus and a 4m USB 2.0 lead up the side of the car to the front. I used the 5v to power the hub at the front, which inturn connects to my keyboard, wifi and touchscreen.



    The wifi is just stuck down with velco, I may move this to inside the piller if theres room at a later date.



    I have attached a usb keyboard in the glovebox.



    The Xenarc screen was stripped down and I fabricated a BMW lookalike housing for it.

    It took me a while to find somewhere to mount the GPS unit, as its a convertable the rear shelf just isnt a option. Then I found somewhere.. under the rear headrest



    This is out of the way and I get good reception now.

    I wired up the dlink direct to my car aerial, it improved the signal no end, its just not as good as a stock headunit, shame really.

    To control it all, I use the touchscreen and keyboard, but the steering wheel controls were wasted so I bought a I-Bus interface from germany.



    This connects directly to the plug that goes in a stock bmw cd changer. I then hunted around for ages.. and ages.. and ages.. finally found the software that I needed to map the steering wheel controls to mediacar. It works awesome makes the whole carputer thing worth while. :-)

    Thats about it for now. I have afew things to perfect, like skins finishing and stuff. but heres a couple of ones I've done so far, ones for day and the others are for night. You might of seen them before somewhere !



    and for night time.. it matchs the colour of the dials :-)



    thats about it for now... here is the finished look so far, you will notice a gap round the dvdrom, this isnt a bad cut job, its where the satnav dvd unit was installed before, I'm going to fill, replace this bit soon.

    The carputer and dvdrom drive.



    This is the amp powering everything.


    and finished off.


    some speakers.


    and the end product :-)


    Let me know if you want anything answering or if you have any ideas how I can improve the install...

    [update]
    I have just altered my motherboard bios to start up with a BMW logo instead of the epia one :-) looks more stock this way

    cheers

    i would be intrested to know where you got the i bus interface and software from, i have a range rover, its all BMW, i am sure i could do the same thing with the wheel controls.
