Audio Systems: MAZDA Millenia Audio Sysyem, mazda millenia, owner manuals

Question
Please what's the difference between the Millenium Ed and the Exc Millenium Ed of the Mazda Millenia audio system?
Thanks

Answer
Sorry, I don't know.  You must consult with the owner manuals of the two cars, I suppose.

You are in Australia where the composition of features is different from the USA, but here in the USA there are generally several options available for the audio; 4 speakers systems, 6 speaker systems and with subs, etc.  Maybe it is the same where you are, but I suspect there are many possible levels of audio systems for each model that were available during any model year.
