It's called Autoleads BMW Multistalk Adapter. Very very rare on ebay, but you can find them in shops as well. www.autoleads.co.uk They make adapters according to the headunit and car model, not generic ones. And yes the steering wheel control works great! Volume up/down, tracks up/down both on audio and mp3 cds. I'll try to get in touch with the seller..

Control software is Centrafuse www.centrafuse.com

The headunit relocation:

Soldered 15 wires on the unit's PCB and another 15 wires on the faceplate. cat5e cable has 4 twisted pairs in it (8 wires total) so you need 2 cat5e cables to run (16 wires total).

so, 2 cat5e cables coming out of the unit, CUT them, and solder the parallel port. Then, run the cables under the carpets etc until you reach the handbrake. Cut the cables again and solder another parallel port.

Took the faceplate and opened it, soldered another 15 wires on its PCB and connected them via parallel port with the ones coming from the trunk. Have a look through the pictures I posted before about the parallel connections.

Head unit (crappy phone camera)


Faceplate:

Blinding install, The PC case looks interesting, looking for somthing tiny for a project of my own (not car related)

Can I ask a question thought, not having a go, just purely out of interest, as I fancy having a go at somthing similar but couldn't put the head unit in like you have as I have Btooth phone unit.

Why did you not go for a USB radio or combined USB TV/Radio would have saved quite a bit of time and effort, remember I'm not having a go or flaming, just wondered.

Very nice diy!

Have you considered integrating your car pc with the IBUS system in your car? You could intercept the steering wheel button signals and use them to control the PC volume. There are many more features that have been uncovered for the E46 as well... including rolling windows up/down, triggering the locks, wipers, lights, etc.

Check out my website for more info ... http://www.HackTheIBUS.com/ ... In a couple of weeks I will be releasing some software that aids in testing all the functionality I described above. You will be able to download it from my website for free!

Cheers!

The headunit is used as an amplifier for the system as well, not only for radio/mp3. I didn't want to install separate amplifier because of the cost and then I would have to change speakers etc. Remember if you don't use a radio, you will need a separate amplifier unit.

I bought the Reslers IBUS Interface USB v5. It costs about $50, is built to order and ships from the UK, so it takes about a month to get it. It plugs into your oem cd changer input (or can be tapped into other places if needed).

Thanks for the replies. I tried to keep the system as OEM as possible;

all OEM wiring is unaffected, no cutting, taping, soldering, drilling on OEM equipment.

kept the oem radio/radio mounting stuff/ sunglass box thingy/ etc for future -want-to-revert-to-original look (only if I ever sell it)

The battery on my car is in the trunk so it's right underneath my carputer.

I got mine from ebay Germany (although was a bit worried getting a LHD version). If you can't find on ebay then I guess dealer is the only choice. If you give them the correct part number I'm sure they can get it for you.

The materials I used are these:

Bondo with fiberglass for the basic shape
Metallic filler for the details
2000 grit sand paper for extra smooth finishing
Universal primer spray for first coatings
Metallic Gloss spray paint to match the interior trim (although I changed my trim to brushed aluminum and looks great as well)

...and around 2 weeks of time

The bezel was based on the guide I found here:
http://www.mp3car.com/vbulletin/fabr...zel-mount.html

although the shape to match the dash lines was based on these plastic trim/adapters found on ebay that allow you to fit an aftermarket HU.

And the final & finishing touch.. Couldn't leave the carputer/radio exposed like that in the trunk so I decided to create some sort of cover.

Solution came with fiber glass! I created the cover first with small pieces of 2mm acrylic and then secured all the pieces together using fiber glass. Strong and light!

Also found some cloth similar to the one BMW uses for the trunk interior. Mother did the stitches. I sprayed glue on the cover so that the cloth sits properly and glued the cloth from the inside.

I also drilled a 120mm hole and put a fan for ventilation which is activated when the computer is turned on.

I didn't have to secure the cover in the trunk, it just sits there perfectly.
