I am pretty new to this but think I have exhausted the search function. Before installing an N1 this weekend, I used a 6800MP with the IPOD adapter. This set up allowed me to browse Artists, Albums, Songs, and playlists. The N1 does none of this obviously. I have read over and over again that N2 and N3 have "better" IPOD control but have not been able to find WHAT the actual difference is. Which brain do I need to goto to get a similar IPOD experience?
