None: Provides no interfacing capabilities.
NMEA Out: Transmits NMEA position, velocity, and navigation data.
Aviation In: The proprietary format used for connection to a Garmin panel-mounted
GPS receiver. This eliminates the need to enter the destination on both units. If the exter-
nal device supports both the Aviation In and MapMX formats, Garmin recommends using
the preferred MapMX format.
Aviation In/NMEA & VHF Out: Receives aviation data and transmits out both NMEA
data, at 9600 baud, and VHF frequency tuning information to a Garmin Nav/Comm radio.
GTX TIS-A In: Receives TIS-A data from a Garmin Mode S transponder or other compat-
ible device.
GTX TIS-A In/NMEA & VHF Out: Receives TIS data and transmits out both NMEA data,
at 9600 baud, and VHF frequency tuning information to a Garmin Nav/Comm radio.
Garmin Data Transfer: The proprietary format used to exchange data with a PC,
weather/traffic device, or another Garmin aera 660.
