When connecting the V16 to the iEFIS Lite you can also connect the EFIS Audio alert output (pin 3 on Power Connector) to the AUX Primary Audio Input (pin 20 on the V16 Radio), to have voice alerts through your headset from the iEFIS. It is recommended that you run this through a panel switch so that you can turn off audio and voice alerts if they become too intrusive.
To Setup the V16 Com Radio on the iEFIS-Lite, first setup MGL NAV/COM 1 radio on the correct serial port in MENU > SYSTEM SETUP MENU > SERIAL PORT ROUTING/ALLOCATIONS:
Then, enable VHF COM 1 in the MENU > SYSTEM SETUP MENU > EQUIPMENT ENABLES menu:
Then, exit setup to save settings and then restart the system (turn power off and on again). Restarts are required between RS-232 allocation changes.

Once connected and operating you can click the arrow on the Radio Status Display and it will open the keypad which has a button to setup the radio:
Note that when the radio control keypad is open the knobs on the EFIS can control various functions:
