Called iPod Support about this same thing because I got a first Gen. Nano and didn't know wheather it was too old or not. The tech guy basially told me the Alpines with the direct iPod interface wrk with every iPod except the new touch. Mine ended up working just fine. So TIFWIW
Thanks for posting that information

, I also was provided this from another forum, corvetteforum.com;
Crutchfield Site Says the following
iPod Full Speed: The CDA-9887 has an iPod Direct Connection mounted on a 4" pigtail on the rear panel. When used with the optional KCE-422i Alpine Full Speed Connection cable (500KCE422i), your receiver can interface with most Apple iPods with a dock connector. You can quickly and easily search through all of the music contained on your iPod by Playlist, Artist, Album, Song, Podcast, Genre, or Composer. You can view artist, album, song, and track number on the head unit's display. When operating your iPod through the Full Speed connection, you can use the Direct Search function in Playlist, Artist, Album, or Song mode to quickly locate your music . Using the unit's preset buttons, you can quickly jump over a designated percentage of your song content (Preset 1: 0% to 16%, Preset 2: 17% to 32%, Preset 3: 33% to 49%, Preset 4: 50% to 66%, Preset 5: 67% to 82%, Preset 6: 83% to 100% of the song library). The unit can be used with the following iPod versions:
Fourth generation iPod: Version 3.1.1 or later
Fifth generation iPod: Version 1.1.2 or later
iPod photo: Version 1.2.1 or later
iPod mini: Version 1.4.1 or later
iPod nano: Version 1.2 or later
That was the first time I have seen it stated version 1.2 or later. Gonna call to be sure tomorrow before I install but hoping it will all be good.
I'll keep this updated,
Pat
