I know someone who has a Bose SoundDock -- it has no input jacks, but only a dock connector that and ipod can connect to. He has another portable audio unit (non-ipod) that he would like to be able to connect to the sounddock, so he can listen to it via the Bose speakers. Is there any type of adapter or add-on that exists that can allow for a typical audio jack input into the bose system? Perhaps something that would convert the ipod dock to either both an ipod dock PLUS an audio input, or just an audio input. I didn't see anything on the Bose site, but thought I'd ask!!
