    Talking 2008 Mini Cooper + Mac Mini = UBERmini [updated photos!]

    So after about 9 months of slowly acquiring all the core components, I've finally decided to take the knife to my Mini and raise its IQ a bit. I decided to take a somewhat unique (and terrifying) approach of shoehorning a Lilliput touchscreen into the speedometer designed for the factory nav system.

    My original plan was to simply retrofit the OEM nav system and call it a day, but I quickly discovered that was going to be an ordeal (replacing the entire front dash wiring harness, talking my way into getting a dealer to recode the BCU to name just a couple things). Turns out doing a car PC would be much simpler (say what?) and, let's be honest, makes it a much more fun project. ;-)

    Anyway, I'll update this thread as I make progress with the install this weekend (starting with some pics as soon as I get home). Wish me luck! :-D

    I'm also keeping a worklog for Nox (the Centrafuse skin) in the Centrafuse forums.

    Step One: The Dislplay

    For the display I purchased a custom Lilliput 669GL from an eBay seller that also provided optically-bonded transflective and capacitive upgrades. In retrospect I think both those things were well worth it (honestly I can't imagine going back to a resistive touchscreen after being spoiled by all the latest and greatest iDevices). I soon found out, however, that the standard 7" size was just slightly too large to fit in the Mini's OEM nav frame. It was close enough that I talked myself into firing up ye olde dremel, and as luck would have it, came out the other side without a broken display.

    First off, here's a quick shot of the original speedo, which I replaced with the alternate speedo designed for the OEM nav system.





    Sadly I didn't remember to start taking photos until the re-assembly stage, but hopefully this will still give you an idea of the amount of trauma that poor little display went through.



    The first thing I had to do was work my way down to the core piece that would hold the LCD panel. Once that was separated, I was able to dremel away enough plastic to be able to slide the display in from one side.







    And here is the display fully crammed into that core plastic piece.



    At this point I ran into a little problem. I discovered that one of the corners of the screen wasn't clearing the mechanics of the speedometer by about 2mm. At this point I was fully invested, so with no other options, I adjusted the position of the screen (despite the tight fit) and again used the dremel to smooth out one of the corners. Probably not the brightest decision of my life, but I was fortunate and sustained no damage to the display's internals.





    Once I had the display fitted, I started buttoning things back up. I was able to reuse the back plate of the OEM display panel to close up the back of the speedometer/display while still allowing the Lilliput's connectors to be accessible.







    The end result was a reasonably clean and self-contained package. Phew!

    Step Two: The Computer

    Obviously for the computer I used a Mac Mini. I thought about using the latest unibody model, but decided it was not only cost-prohibitive (no need for that much horespower), but the form factor was also not optimal. The new ones are wider and flatter and have the AC/DC power brick integrated into the machine. The end result was that it wouldn't fit into the "secret compartment" intended for the CD changer option, would be more expensive, and would have the built-in AC power brick needlessly taking up space.

    So instead, I went for the cheapest Mac Mini I could find that still had an intel CPU.

    The first thing to do was to crack the case open and install the power button splitter for the CarNetix P1900 power supply.



    I found it to be easiest to feed it through one of the vents on the bottom.



    Once that was complete, I removed the "secret compartment" assembly from the car and modified it to accommodate the Mac Mini. To do this, I removed the hollow insert inside the housing, and found that the Mac fit perfectly in the open space (with some extra space on either side).



    I decided to set it up so I could remove the computer easily, rather than somehow mounting it semi-permanently. My solution was to set up the compartment so that I could slide the mini in and out. To prevent the mini from sliding too far inward, I glued an extra strip of plastic across the back to give it a lip (which I also had to modify with the dremel to ensure all the ports on the back were still accessible).



    You can probably see how I dealt with the extra space on the sides. I basically picked up some of that foam you use for window A/C units and used some double-sided foam tape to stick it to either side. This gave me a nice snug fit that still allowed me to freely slide the mini out of the compartment without too much trouble.

    At this point, I ensured all the various cables were zip-tied together to form a home-made harness (with enough slack to allow for the computer to slide out completely), connected everything to the back of the computer, and re-installed the secret compartment.





    Once installed, it looked fairly clean and left the Mini still easily accessible should I need to remove it from the car for software updates, maintenance, etc.

    Step Three: The Peripherals

    This isn't quite the order in which I put things together, but to keep my posts coherent, I'm grouping the peripherals into a single section.

    1. Andrea SuperBeam Microphone Array

    Sadly, although my car had the OEM bluetooth option, some research revealed I wouldn't be able to tap into the factory microphone. Instead, I removed it completely, and replaced it with the guts from an Andrea microphone. I had hoped to keep the casing on and simply hide it somewhere, but I ended up opting for the more complicated solution.



    As it turns out, there were two perfectly sized openings in the headliner module that housed the factory microphone (among other things). One of them was occupied by the original mic, so after removing it, I got creative and used some more of that foam to snugly fit the Andrea mic heads into place.







    The next step was to cut away some of the filler plastic that I found after removing the headliner module. A few passes with the dremel and I had a perfectly shaped hole to allow the excess mic electronics to fit.







    The final step was to route the mic wire behind the headliner and down the A-pillar and into the back of the secret compartment. This turned out to be easier than I expected, as there was plenty of room (and holes) for the wire to reach its destination.







    2. GPS

    I didn't end up with any shots of the GPS install, but it was more or less the same as the mic install. I basically tucked it inside the headliner and routed the USB cable down the A-pillar and over to the back of the Mac. So just pretend the previous shots were for the GPS dongle and you'll get the same effect. :-D

    3. HD Radio

    For radio I picked up one of the Visteon HD radio units and the USB adapter cable made by Mitch in the MP3car store. I ended up mounting it directly beneath the OEM radio unit for simplicity, and connected up all the corresponding cables.







    Once the radio was installed, I also connected up an MJS USB Audio selector so I could switch from the radio as an input to the AUX input. For the AUX input, I spliced in a standard minijack line into the back of the OEM AUX input (below the climate controls). In fact, I also did the same for the OEM USB input, effectively giving me a USB port for the Mac Mini that was easily accessible and visually indistinguishable from the OEM setup. No pics for the USB or AUX yet, but I'll see if I can track them down and post them up.

    Super clean. Can't wait to see what else you have in store. Also, I didn't know that Mitch's UAS had OS X drivers.

    Fantastic! You did a great job on fitting the 669 into the speedometer, and converting the entire assembly to the OEM NAV configuration. Keep up the excellent work!

    Does the oem nav system really go 'inside' of the speedo? That is slick, great install!

    Yep, it sure does. NAV, various onscreen displays. It looks pretty good, actually.
