Radio upgrade for 2000 MPV ES

Hi,

I recently bought a 2000 MPV ES with a single CD/cassette stereo system. I'm looking to upgrade to a multi-disc in-dash unit, with a cassette player, with minimal fuss... lol.

I think that the optional 6-disc unit for the 2000 MPV lacked a cassette, (at least the one I saw on e-bay did) so I was wondering if another Mazda model had plug and play capability with my current set-up.

I was specifically wondering about the 2000 Millenia Bose unit.

A picture of the unit is at the e-bay link below.

Any help would be greatly appreciated!

Thanks,
Eric
