I am looking at the Grand Concerto and have the same question as the o.p. As I am ONLY looking at connecting a Nuvo tuner to the G/C (and possibly the Nuvo iPod dock) and connecting speaker wires and keypads, WHY is the IR Learning Center required, or IS it? I have bought nothing yet, but getting quotes from several companies here for my new home, and I prefer the Nuvo to the other systems, but I also hate the thought of paying $$$ in install fees to connect a few wires!!! I don't mind paying for expertise WHEN NEEDED, but I HATE paying for someone to do the equivalent of plugging in a power cord.
I guess my theory is that if I were connecting a cd changer, a satellite box, and an outside tuner (like an outside XM tuner), then I see the need for the IR Learner and custom installation to make it all work. But if all I'm doing is plugging together Nuvo components and connecting wire and power cords, why the heck is anything else needed? What am I missing?
