It does sound pretty good (esp if you use apple lossless, better sound than mp3's on the SD/HDD).
Doesn't add any extra features for MDI playback that i know of but may brows folders/songs a bit quicker than the original version of the RCD510 (mine came with the newer RCD510 that works quicker and has different buttons ie removed TIM (traffic info) and has an AM/FM button etc).
