in theroy, you could get 3 adapters from alpine, one Honda/Acura to Alpine changer adapter, one M-bus to Ai-Net adapter and an Alpine auxillary input adapter.
It would seem to me that would work... but dont quote me on it.
Also, email
ron@streeteffectz.com about a honda/acura input adapter... I think I remember him saying he has something... I think it was around $70.
