Thanks Frank,

Good instructions.

I do have some questions after the install...here we go:
1) I lose my music database after transferring and renaming the init & IR code files via Hyperterminal. After the last player reboot, the player rebuilds the database and I see no inventory. After flashing back to a standard empeg kernel, the database is restored. I'm not sure what's happening here - you should know that I'm using very long file names. The player plays the inventory on the player, but displays "No title" along with the time.
2) The volume UP is disabled using your suggested empeg_ircodes. The DOWN volume is still active. The volume on the empeg would gradually creep down as you adjusted volume on the Kenwood head unit.
3) The TAPE (AUX) button seems to be disabled.

We're almost there. I would appreciate any suggestions on the music database vanishing.
