- Android sound works for ~1 second when the audio is set to AUX then quickly switches to BMW's FM tuner.
- Running an AUX cable to the glove box doesn't change anything.
Anyone have any ideas as to why it is switching from AUX to FM magically without me asking it to? I've reached out to the seller but I'm not particularly hopeful..

Well the seller came through beautifully.
Turns out the Android headunit binds a "sound key" to one of the preset keys, 8 for my firmware version. This can be changed in some versions but not mine.
The fix was simply to bind AUX to the number 8 preset, also means you can switch to headunit audio quickly as a bonus.
