I only tried the unit for a few minutes with my DICE unit when I first got it and had no playlists synced. Now that I've had the chance to sych it and play with it... well...
The DICE does not support charging, does not display track listings, does not support anytype of browsing (track, playlist, album, chapter). If you put it in either chapter or album mode (CD 3 or 4) and press the > button it will randomly play another track.
So it will play, but functionality is pretty much useless. I guess if you just fill it with music and don't care what you hear it's all right, but otherwise my experience with it is a very strong "Don't Buy" for use with iPhone. Guess I'll keep using my 3rd generation 40G ipod for music in the Z.
Interesting thing is I was right about the panasonic aftermarket head unit I have in my E30, it supports browsing by playlist, artist, album; displays track data; but doesn't support charging.
Any DICE users with an iPhone I'd love some feedback regarding any work arounds / firmware updates you've found to increase functionality. Tom any suggestions for us?
