Okay i am thinkin about gettin the sony MD 7700 from japan. it doesnt play mp3s or dvds which is a big flaw considering the $750 price tag. Neways i was wondering if i add a mp3/cd changer in the glove department.. will i be able to play mp3s on the unit? (also does it matter that the HU is from japan and the changer is US).
Well yea thats my question... same question with a dvd/mp3/cd changer as well.

 

The 7700 is a uni-link controller...so yes, if you cd changer supports MP3 playback, the 7700 will play it back.
