Thank you. I don't know how I missed it. I think I did most of my searching in the DVP-CX860 manual which doesn't have this information except to say that when a CD changer is connected, you should set the "command mode" of the connected CD changer to 3.

So now, I'm wondering if the old DVP-CX860 also supports the same functionality? I see that the DVP-CX985V also does.

I'll look at my remote and DVP-CX860 changer when I get home tonight to see if it has the switches. From looking at the manual on-line, I don't think it does.
