  • Hyundai Tiburon 2006

    My car PC installation has reached a semi-stable state and so it's time for some pictures and details. This is a complete in-dash installation, leaving the back seats for passengers and the trunk for scuba gear

    Here's the stock radio- as you can see the second DIN slot is covered by the Tiburon logo:

    And here's the result:

    Now for some details:
    The system is an Epia CN-10000 with a non-motorized (but very swivel-friendly) screen. Power is supplied by a M1-ATX. But first we need to get battery power into the dash. Starting from the + terminal the curious yellow wire snakes its way towards the window wipers:

    Through a hole down into the wheel well (usually hidden behind some plastic) it curves towards the driver side door

    and after going through a rubber grommet finds itself near the brake pedal :

    Some zippies and a few inches of tape later it comes out in the center dash (lower left corner)

    There's a chassis connector nearby (top center in previous photo) which we can tap to provide ground to the M1. A very annoying support beam is located in the top right- but at least we can use it to hold the M1 mounted by two screws onto some spare PCB (top right):

    Another bar going horizontally across the dash is meant to support Hyundai's Infinity radio system. Since I don't have said system I removed some of the screws, tilted the bar down to get more space. As you can see above it provides a good mounting spot for the hard drive as well. The previous picture shows my first HDD mounting attempt. Unfortunately the fragile SATA connector extending upwards got decapitated by the mainboard later. My final install has the hard drive in the same spot, but mounted horizontally instead, so the cables and connectors are protected behind the bar instead.

    Time for a quick detour; the screen when not retracted has "LCD Touch Screen" written in bright letters on its case. Not wishing to give thieves a reason to break into my car this lettering had to go. A few screws and sticky tape hold the front piece in place. The black backing got several Dremel sanding treatments followed by several coats of black spray paint before being reassembled:

    The original radio housing looks as though it could hold the screen as well as the radio but unfortunately it can not. So instead I ordered Hyundai's Infinity mounting brackets. Of course they don't adhere to any standards and required significant modification. In the next photo you can see the right mounting bracket with holes added and several curved parts flattened out. The screws had to be sawed off so as not to interfere with screen retraction. Getting these parts just right took A VERY LONG TIME..

    The stock Kenwood radio has an AuxIn connector but it uses a weird DIN connector. You can buy RCA adapters at BestBuy for $25. Rather than being robbed I bought the appropriate DIN plug on ebay and soldered a 10k resistor and mini stereo plug on it. Here's the $4 version prior to assembly:

    Since we have very limited space in the dash and because of all these support beams the main board has to be in just the right position above the DIN slots. I took an old PC case and cut out its aluminium base which already has the ATX posts in the right spot. All it requires is drilling 3 additional screws into the screen housing like so:

    Then we carefully slide the whole arrangement into place, while trying to plug in VGA and USB connectors on the right. Several bloody knuckles later it looks like this:

    I want to switch the system with a nice OEM switch. Unfortunately those are not available in the US and I had to import one from Korea. When I finally got it, it turned out to be a push button instead of a toggle switch. So I had to design a PCB turning it into a toggle instead:

    The button is a little too big and sticks out but at least it has the same look & feel as the rest of the car and spiffy lights when armed and active. (TBD: I don't have a photo of the final button installation yet)

    For voice recognition we need a microphone :

    I have used Logitech's USB version with the mic mounted at the front ceiling and its AD converter board stored away above the fuse box and behind the push button (not installed in the picture- you can see a hole though). You can also see the ACC wire and M1 signal lead sticking out:

    The same arrangement on the passenger side allows for adding a 4-port USB hub which connects the Holux GPS receiver, and a 802.11b stick. It's also proven useful for connecting a keyboard when BIOS settings need to be changed :

    That's about it for show & tell; maybe a few more details and plans for the future: my goal was having a customizable voice recognition GPS system. During operation I have Google Earth and CoPilot 10 running. One for guidance, one for looks. Voice recognition is done by Responding Heads plus a couple of AutoIt scripts. This works very well at <55MPH but refuses to listen when going faster. Networking is provided by Boingo and an Ashton WLAN stick. Unfortunately the Ashton drivers are crap and occasionally fail to resume from hibernate. I am hoping that devcon will fix this. The on-screen keyboard software I use is amazing- but I can't for the life of me remember its name. Just search the forum for a previous post by me linking to it. An OBD2 USB interface is already installed - I just have to write the software for a realtime MPG output.
    Total project time: ~3 months.

    To-do list:
    a) get a GPS antenna and hide the GPS module inside the dash. Currently it has to rest on top of it to get a signal.
    b) build a PCB to interface the garage door opener via serial port and add an "Open Sesame" command to Responding Heads

      killer. you put a lot of time and effort into your project and it looks like it's paying off in spades. Thanks for the pics.
