SDK to develope software for Blue&Me
I have been currently looking into this myself. The system is based on Windows Mobile Automotive.
If you download the EcoDrive software and extract the CAB file, you'll find some executable files. File 0000eDes.006 seems to be the main executable. It's written in .NET. That means .NET Compact Framework is also available.
Use the Red Gate Reflector to disassemble it. You'll get a rough picture, how the software is written.
The SDK you need to make new software seems to be the Microsoft Windows CE Platform SDK Automotive Edition, I think. Sadly though, I have not been able to find it on MS download site.

Its a closed SDK sadly I think, I'd imagine only available to the manufacturers using the system
