i think you're going to be out of luck finding a hard-wired remote for a jbl, but i'm currently looking into one of these for my kenwood head unit:
http://www.wakeworld.com/MB/Discus/messages/3183/277834.html?1137510853 in my case, i don't want to give up the aux/cd changer input port on my head unit which would be required to use the kenwood branded product so this looks to be my only option.
the only way this works is that if your current unit has an infrared wireless remote and that it operates within the specified frequency range.
