It looks like things aren't quite so simple in Harman Kardon land.

Apparently the "second remote" uses the same codes as the first remote -- you're supposed to run an IR extender (not included, another $60 extra) in the second room, and plug it into the back.

So, this would work for me, but I don't want to run the wire and buy the extender.

The other thing is that it's possible to control the second room program from the main IR and remote, but it's a complex sequence of menus. And I don't really want a separate activity, I just want soft-key buttons ("kitchen on", "kitchen off") on the "Sound" menu of every activity.

That's why I'm wondering if there's anyone here who actually has a Harman Kardon 635 and is happily controlling a second zone using a Harmony remote.
