    Have you got one of these new switched ALPs encoders?

    If so I would be interested in knowing how you get them here in good old blighty.

    Personally, I think that having a large wheel almost like a scroll wheel sticking out on the side of the monitor would be very slick. It could have some heft to it so there would be a bit of inertia too. It would be very much like paging through a book for scrolling through songs.

    where heft == Griffin's Powermate?
    many are trying to get away from that much heft... but I get your point and agree w/ it on some levels.

    I've seen some larger (like the Powermate) knobs that can slide(not tilt like joystick) in 4 directions... rotate and momentary push(click).. now, if it had detents, THAT would be pretty nifty for ye'ol' ∙CarPC

    What about instead of hooking up to a mouses scroll wheel hook it up to a keyboard encoder rigged to send keystrokes. This would give a lot more flexibility and more possibilities for customization

    The keystrokes could then just correspond to whatever hotkeys are used in your frontend program or generic keys used for up/down scrolling

    Hey, I've started doing something very similar in my Audi, aslo.

    Here's what I have so far:

    Removed Rear Center Console:

    The rotary knob/selector and 4 soft buttons will be located down from the cigarette ligher.

    Space Underneath the Console:

    Notice how much empty space is found down there...

    Sketch of what I want to achieve:

    The rotary knob/selector will be made out of another cigarette lighter (hopefully identical to the one I've got in the car).
    It will be mounted in the original socket and backlit by the LED I took out of the mouse (hopefully 1 is enough).
    The socket's negative terminal will serve as a mounting point for the PCB.
    The PBC will hold the Generic Mouse Encoder (if I find it to be too fragile, or brake it during installation, I will opt for a different, more durable encoder).
    The PBC will also hold a switch that will be wired to the mouse's SWM (middle click switch), which will make the knob work also as a selector/soft button when pressed upon. NOTE: Since the cigarette lighter has a built it spring, there shouldn't be a problem getting it back to Open Position.
    There will be 4 soft buttons positioned in the way I illustrated above. They will be primarily used for Play/Pause, Stop, Next, Previous (Clockwise from the top left). The reason I'm allowed to use 4 more buttons is because I came across a 5-button mouse.

    Mouse:

    I de-soldered all of the switches and soldered PS2 connecter into the board so I could easily un-plug and re-plug the device, if needed.
    Notice the extra two buttons to the left of the mouse.

    Newsflash: Take a look at my unsold stuff above, thanks!
    Up Next: Make an OBD to Serial cable & Redo the "MMI buttons"

    Interesting idea. If the monitor is in each, its worth a try. For me, the monitor wasn't. I think I have seen some early HP laptops with your suggestion.

    @DJiK

    As you know, thats the same gearbox console as in my coupe. Your idea re: using the lighter is very stealth. If the mouse encoder isn't man enough its easy to wire in a bigger encoder. As you said, there is plenty of space underneath for the mouse PCB (I put mine in a small ABS box) Keep us posted with updates!
