I've a Japanese domestic market Prius G selection that comes with in-dash 6 CD changer. I'd like to install a Nokia or Parrot bluetooth car kit but could not be sure if I need any special adapters to connect to mute & auxiliary input connectors of the audio system. Also, I notice that there are people talking about getting Parrot to work but have yet to see one on Nokia. Any reasons? Any one using the Parrot MK6100? What about the Nokia CD-20W or the CK-300? Any one knows where to get the diagrams for the in-dash 6 CD changer? Any advice will be greatly appreciated. Tks.
