I just come across this and though I may share, plenty of AUX questions here so I choosen most recent one :P
MMMi set for premium audio
It says its "in production" with pre-orders available, but to my knowledge its the first system designed specifically for premium (Dolby P.L.) sound system.
Provides only AUX but fully integrated with MOST and much cheaper than BP/GROM units. And I reckon much better quality sound than wired FM modulator.
thoughts?
