All functions of the SkyView system (setting comm frequencies, autopilot control, heading and altitude bugs, altimeter setting, etc.) can be done via the touchscreen interface. The only function-specific control module that's required is the comm radio head, as the EFIS cannot control radio volume. See this post by a Dynon tech on their forum.
