    I have a CD stacker by itself, not 100% sure if it will fit the E39, I think it came out of my E91 (bad memory) but I can try it on my E39  tomorrow and let you know if you find a radio unit without cd stacker.

    Control protocol different on e91 and not downwardly compatable dispite similar appearances to Ibus based units.

  2. Thanks Scott

     

    The media software is quite well developed (kodi with large fonts) the serial controller on the pi bus is looking at the ibus  for the hex codes from BMW board monitor controls. Basically the media centre is controlled by the bmw buttons and knobs so no need for iphone control.

    kodi is quite good. You can run different skins and choose menu options. Playlists etc. It can also be remotes controlled via iphone app if needed. There is also support for airplay , but a quick check showed issues with ios 9.3 on my phone.

    The wider system has some good features. When powered up at home it will WiFi attach to my home storage system and sync any new music libraries. It will also rip CDs and convert to flack which might be handy.

    Audio app looks like this http://kodi.wiki/view/Music_playback

     

     

     

     


  3. added all USB , sata, audio and power cabling

    Mounted raspberry pi. Used standard PCB header connectors from Jaycar electronics so everything can unplug from pibus board.

    Bluray player had small m2 screws. Drilled holes in old 3.5 drive bay bracket and mounted player.

    Back

    Added Molex connector which has input from reverse light and output trigger for BMW video module. Basically the piboard tricks the video module into thinking a reverse cam has been trigger. It will either output camera or media centre to BMW board monitor.

    Last bit was adding a USB Async sabre audio DAC. Its not normally needed but my aftermarket DSP has a digital input. This means I can go digital audio straight to the processor from music content stored on the Raspberry. It will avoid the audio from going through another three sets of analogue audio stages before hitting the amps. It should in theory provide very low distortion through to the audio amps.

  4. Re-used factory connection  sockets for changer audio output and power / ibus . System will require about 3 amps at 12 volts when running. Existing cd charger power wire ok at this level.

    Old alpine pcb

    Replaced with audio and raspberry pi and USB powered hub power.

    Pi bus daughter board for raspberry pi. Clever design. Has microcontroller that listens for ibus signals such as infosystem on , boardmointor controls , steering wheel audio buttons etc. It controls start up and shutdown of Raspberry, audiophile grade audio which is feed back into factory stereo replacing cd changer. Also does video switching when selected. Either reverse camera or raspberry pi running openekec OS and xbmc media centre.

    More detail at http://pibus.info/

    Added an old CPU fan to the case. Just in case ......get it .......

    Also a couple of RCA sockets for reverse camera input and system video output.

    EDIT , fan didn't work out , CPU fan far too noisy. Could hear it inside car. Has been disconnected but unit temp ok on PI without it.

  5. On the manual subject a period car needs to be manual to typify the experience. I'd hate a auto or SMG version in my 60s Mini's. Wouldn't get the best out of the limited power in one of them. The other wouldn't  seem right with LSD, straight cut cr box and drop gears and the mechanical raucous that will go on.

    Only good bit was the Rimutaka hill and it would have been better on a motorbike in summer.

     

    Ruined by the PC brigade, Did you notice the double yellow lines  bridge to bridge ? Cops hiding in trees during  summer. Pinging  any biker that dares to overtake the car traveling at 30 kph with half a km of traffic held behind it.

  7. Sounding like USA is about to get the first batch of 45000 air bags for the second recall.

    These are large campaigns to gear up for so I wouldn't expect it to be over night.

    Local dealer replaced my passenger one during a warrant. No charges where applied.

  8. I think the issue might have been BMW understating the 1m figures as it had similar power and more torque than the more expensive e90 m3s

    Eitherway the 1m is a fantastic.car . Ironically the USA LHD versions could be brought for Nz$50,000 new from the dealer when I was in San Deigo 2012 . Bargain car at that price.


  9. Dyno run was at a bmwcc event in wellington 1M was highest BMW on the day by a clear margin. Just over 400 hp and 550nm. Second was a SLK32 at 396hp (Had been overdriven and cold air intake) My e46 was 305hp 330nms from memory and another modified e46 m3 did 275hp but run limited to 7000rpm as running too rich

    There was a 335i but it wouldn't rev out on dyno so we missed out on the differences between turbo engines.

    BTW 135s jumped to 235kw in some counties. (135is in USA for example)
