Mazda seems to be hyping up their "modular" stereo system.
It looks like you can put different stuff in the upper (CD)
compartment and the lower (Cassette) compartment. I don't
know that much about it; I just saw pictures in some of the
promotional literature.

Anybody know if there is a CD/MP3 player that can be swapped
into the upper compartment? Does the MP3 player from the
Protege MP3 fit in there? Or is that a custom job?

Thanks.

 

The quick reply is that the Prot-MP3 has a "custom" install. They were equiped with either a Kenwood Z919 or later with a Kenwood Z828 headunit.

The following thread has a lot more on it:

There is not a Mazda modular option that allows for MP3 playback.
