A:Answer Yes, the Kenwood KC-206 is listed in the Logitech Harmony database so it should work well. In addition, in the event that a feature from the original remote for the device is not installed when going through the setup process the Harmony 350 has a learning feature the allows it to learn additional commands from the original remote. Finally, even a device is not listed in the master database there is a process to teach the Harmony from the original device one command at a time. This process would be tedious, but after it is done one time it would allow the Harmony to control all the features of the device that could be controlled by the original remote.
EXCEPTION: The Harmony 350 transmits only IR commands, not RF. If a device remote is RF only (i.e., does not have to be pointed at the device) the Harmony 350 would not work. Such situations are somewhat rare for audio/visual entertainment devices, but there may be a few and I suspect they might become more common in the future.
