imBMW is .NET Micro Framework and hardware project. It was started to add custom features to cars with iBus interface such as '91-'10 BMWs and some related models. Then CAN BUS support was added to integrate with newer BMWs.

The Original imBMW V1 device uses FEZ Mini, connects with iPod/iPhone via headset cable to be controlled by BMW audio system.

The Next Gen imBMW V2 device, that uses STM32F405 based FEZ Cerb40 II, is a *duino-compatible iBus-ready board. It could be used with any shield, for example with imBMW Bluetooth OVC3860 or Bluetooth Pro Bluegiga WT32 Shields for wireless stereo audio connection to BMW audio system, handsfree calls and even for forwarding iBus via Bluetooth to smartphones, tablets and PCs - imBMW already has a library for Universal Windows Platform (UWP). There is also Diagnostic Bus DS2 support using regular OBD II to USB adapter, that allows Engine Control Unit plus additional sensors logging and wireless Bluetooth dashboard. Furthermore, CAN BUS support was added for sniffing and integrating with CAN modules of all BMWs since the end 90's till latest BMW models including i-series EVs.
