If you plan to use NavCoder, then you can build a simple interface yourself. Or, you can buy a great one that is already built from
IBUS Interface for BMW cars. I recommend the latter-- it is what I have. The NavCoder I-Bus interface connects to your I-Bus, typically at the CD Changer plug. It does not use the OBD II plug under the steering column.
You can get a BMW diagnostics cable from a few suppliers in China like this one
Ediabas OBD2 Interface obdchina: auto diagnostic tools expert. You did not mention the year and model of your car, and that is important to know whether you would need the OBD II plug or the 20-pin under hood plug. Also, you will need BMW's proprietary diagnostics software to use this cable.
