Hi all

I am looking at doing something similar in my M3. I have already got my Pi (it is just sat around looking at me). i have an Arduino also so I am looking to try and use this. If anyone has any experience with Arduino and Ibus let me know your experiences.

I am still in the early stages but will keep updated on progress.

My background is more software than hardware, so will be a bit slow on the electronics side.

An Arduino is basically an Atmel AVR that's a bit more powerful than the processor I used. I guess you could use it, but you still need to translate the 12V ibus into what-ever voltage Arduino runs at - you can't plug it straight in. Then write your own (non-trival) firmware.

If you really want a shortcut and simplified version, then use a Resler USB interface straight to the R.Pi (google Resler IBUS). It would miss some features though like reverse-camera switching & automatic power on/off.

From public & private messages I think about 3-4 people are trying to reproduce my project. The pattern seems to be the all know software but struggle a bit with electronics. Who'll win the race to get it working first?

While on the subject of arduino,

Thank you for the reply.
After further research I think I will be going down the Resler route and just write some code to interface with it.

I have already got my PI setup with XBMC and a wireless dongle installed so that I can Airplay straight from my phone.

Going to order a USB interface in the next couple of days.

I will keep the updates coming ...

The hardware has power even if you lock the car, just gotta add some software that gracefully shuts down after ~5 mins of inactivity.



Sure I'll make you one. It took me 6 months, so the invoice will be $50,000 or so (though there's $10 worth of parts on the board . If you're handy with a soldering iron and have lots of patience I can give you the plans.
Sorry to bother you guys but is there anyway I can view a monitor from the rear. nicgala Thanks

There's been some confusion about how to connect this all up, so I made this giant diagram:

Hello) i am from Russia) and sorry for my English=) I install raspberry pi in my e38, connect video to RV Camera input, audio instead of TAPE and hand made Ibus adapter. I install cis-ibus and it work very well, but it slow and i want to use XBMC) can i use your pibus software in my case? can i switch between bmw menu and xbmc with MODE button (XBMC in TAPE mode)?

Not without modifying the pibus software a lot. It looks for the text "CDC 1-04" to switch the video and keyboard. It also does cd-changer emulation, you'd have to disable it. It also does re-transmit on the ibus, who knows if your adapter needs it, is it a TH3122 or something custom?

Unless you can program in C, the short answer would be no. Have you tried openBM on some German forums?

you have cd changer emulation? if i connect audio instead of CD changer (with S/PDIF) there is a chance it will work?

OpenBM have not switch MODE between BMW menu and xbmc, gateaway works well, but i can not use radio, TV, Navi etc.

Yes it has cdc emulation. It might work. My car doesn't have S/PDIF or a DSP, so I'm not sure - I use analog CDC input. What is your hand-made ibus interface? How do you control pin 17 (NTSC trigger)?

OpenELEC doesn't have many drivers for extra hardware. Maybe try Raspbian? Or build my simple ibus interface straight to the PI's pin header, no drivers needed:

A few people are asking where to buy all the parts to build this thing.
There is an Excel spreadsheet on my webpage listing all the parts - this is more accurate than the schematic diagram.

My Ride: Range Rover l322
Hi all,

just found this project and I'm really excited about it.
I own a Range Rover l322, which is manufactured by BMW and equipped with the same radio.
Currently I have a MK3 navigation, but I'm planning to upgrade to a MK4 soon.

Do you know if this system would work with a DSP amp? I Don't have a coax-connection on my CD-changer.

I'm a software engineer and as a hobby I like to play around with electronics. I wouldn't mind to do some hacking on it before it works.

thanks!
Theo
