Petter Bellander / Mbed 2 deprecated Saab-BT

Simulated the CD changer of a Saab to implement a bluetooth connection to the car stereo. Control of playback device (phone) with steering wheel buttons. Needs a RN52 bluetooth transciever and a CAN transiever. So far only audio playback and control via steering wheel buttons implemented. Hands free calling planned.
