Raspberry Pi as CD changer in pre 09/2002 E46 BMW 320i touring
Posted by jpluimers on 2018/10/05
My pre 09/2002 E46 BMW 320i touring didn’t come with a CD-changer, and since the Business CD head-unit didn’t support the regular AUX mechanisms (see links further below), I’m researching how to add a Raspberry Pi as CD-changer.
A few things I want to accomplish:
- Raspberry Pi powers up as it has ignition signal
- Raspberry Pi powers down soon after it has lost ignition signal
- Connected via the CD-changer connectors (iBus and audio) in the back
