I guess my question is does it work? Looking at the TKP-100 single gang keypads, there are only buttons and no LCD screen to display anything. For example, if you wanted to listen to Sirius, turning on a zone with it's (TKP-100) keypad, how would you know what channel you're tuned to? How would you change the channel with the keypad? Can a keypad button be programmed to select a specific channel or toggle through a bank of pre-set favorite channels? This is critical because if using the system requires walking to another room to change the channel, it won't work for me. Similarly, how is the iPod controlled via the TKP-100 keypad?
7 of my 8 current zones use a single gang keypad and I would rather not have to expand all of them to double gang (I could install one KTP-2000 in a double gang space I have in one of the zones) unless absolutely necessary.
