NAV/COM 1 + 2
Two GNC 215-style NAV/COMs, NAV/COM 1 over NAV/COM 2, squeezed into the space of one 2 x 1 module. Each unit works exactly as the single NAV/COM.

Features
- NAV/COM 1 on top, NAV/COM 2 below, each with its own knob, keys and display
- COM active/standby with station names, TX/RX indications
- NAV active with ident, DME distance, built-in CDI with TO/FROM arrow and NAV flag
- OBS set from each unit (NAV 1 course and NAV 2 course)
- At night the faceplate, keys and knobs take the red flood light while the display keeps its own colors, dimmed; the glareshield's warm light falls on the faceplate too when its dimmer is up (Settings > Dimmers > Glareshield, off by default)
- The display goes dark when the aircraft's avionics power is off
On the iPad
- Same as the NAV/COM on each unit: drag the dual knob (outer MHz, inner channel), tap it to switch COM/NAV
- Tap a pane of the screen to choose COM or NAV; swap key swaps active/standby; MENU for the OBS

Simulator data
What the Hub reads from the simulator for this instrument, and what the instrument sends back. Names are the simulators' own: MSFS SimVars and events, X-Plane datarefs and commands.

Add-on aircraft with their own systems may use other variables; the Hub reads the standard ones.
Changes
The instrument's version counts what its faces share (the case, the mechanism, the data, the sounds); a face's own version counts that face alone.
