I should have been a little more clear- my intent is to mount in the dash above the Pioneer (Explorers have a double DIN slot). I think I have seen the page you are referring to somewhere, but like you said, it would cause all kinds of problems with both units responding to the same remote. That is why I was hoping I could connect to the IP-Bus, this way the Empeg would ignore the remote, but respond to the IP-bus, which would be controlled by the remote. Pioneer uses a device address of some sort w/ it's changers (up to 4 can be connected to 1 head), I figured I could get the Empeg to emulate one the device addresses and respond to simple play,stop,next/prev track/cd, etc. But without an understanding of their physical data link, I don't think I'll make too much progress...
