Took over three days, but I've finally got my NX-5700/5700/5800 stack and KCH-20 installed in my 2016 Honda Pilot. Pictures coming soon. But first, is there any shared wisdom about key assignments on the control head? Who's using what for RF deck selection vs. zone selection? I think I want buttons for direct OST, zone select, and RF deck select and talkaround at the very least, but curious how others have set it up.
