Description

provides MP3, Bluetooth and FM radio compatibility as well as some misc E39 interface lines and an output to the new digital instrument cluster.

Note this is part of a big project to electrify a BMW E39.It may work or may not so I wont be publishing many details until I know how it works out.

Version 2 had errors and not enough IO for K bus so have moved BMW processing to daughter board and Simplified the Media Processing Board, two CPUs are interfaced using I2C
