I use firmware 2b2 and have no issues going through my playlists. I have about 20 active at any one time, I scroll through them with my steering wheel controls. I just hit selection 6, push down on the steering wheel to get to playlist, press and hold to get the list. I have got it down so I don't even look at the nav other than picking the playlist I want. My library is about 7000 songs. My only annoyance is not being able to control shuffle. There is no question that this is currently the best solution hands down.

I am constantly amazed at the quality of the sound, clearly better than my CD changer was.

I am glad to hear that an upgrade is coming, there is clearly room for improvement, but 2b2 is useable.
