Sorry I haven't had time to investigate.

I think the remote you have is as good as any for this task. The issue is figuring out the right advanced code.

Rob probably knows this better than I do. He often doesn't read this forum, so you might want to ask for help with "5 digit EFC numbers for Audio/1023" in Rob's forum at

And be sure to include a link back to this thread so he won't need to re ask anything already discussed here.

That will probably get Rob's attention or maybe some other expert who understands the 5 digit EFC numbers as they relate to Pioneer receivers.
