I have been selling and programing urc for many years. Started with the old reliable mx500/600 moved up to the mx700/800 than the mx850 which i still love. Now I almost always sell the mx900/mrf350's... bullet proof... I just wish the mx900 had an option to activate the light when tilted or a button is pressed. Anyway, the reason for this thread, I have mastered the programing of these remotes. I am not the best on a computer. How much more knowledge do I need on the computer to program the mx3000? I want to be able to offer my clients a nice touchscreen... thanks..
