Hmmm. This one is my fault. I definitely didn't design the program with the Mk1 in mind.

Tell you what, I don't want to tie up any of the 4 front panel buttons with my menus, so I'll add suport in a future version for IR codes (probably configurable) to activate the menu and select options. Thinking aloud here, the default to activate the menu will probably be the "CD" button (on both Rio and Kenwood remotes) and the default to select options will probably be Vol+ and Vol- on both remotes.

No discrimination towards Mk1 users intended... Just didn't think of it.
