Hi. I am trying to find a Canadian dealer in order to buy an MCU for a Nuvo Grand Concerto. I have the Concerto unit ( which was misrepresented to me when i bought it), with the new touchscreen oled keypads, they aren't compatible. If I can find a Grand Concerto MCU, then upgrade it, everything should be fine I hope. Anyone know of a dealer who can sell me one? I am in Winnipeg Manitoba. Thanks!
