Ref the 40ELK if it helps this is what I have found with the NW-A 3000: - Only two lines of the three line display work - Stop, start, volume, and forward one track and backward one track also work Thats about it. The moving up one level function that worked with my NWHD1 (eg changing from track view to Album view) doesnt work. Essentially you get much as the same functions as the remote without a display, but with the ability to see the track name, or artist name, or album name along with time elapsed, track number etc Does this help?
