GARMIN DGPS—used to connect the GPSMAP 495 with a
Garmin DGPS beacon receiver.
Garmin Remote Sonar—supports the input/output of a Garmin
remote sonar device.
NMEA In/NMEA Out—supports the input/output of standard
NMEA 0183 version 3.01 data and sonar NMEA input support
for the DPT, MTW, and VHW sentences.
Aviation In—the proprietary format used for connection to a
Garmin panel-mounted GPS receiver. Allows the GPSMAP 495
to show a Go To or route selected on the panel-mounted GPS
receiver. This eliminates the need to enter the destination on both
units.
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. See
.
TIS In—receives TIS data from a Garmin Mode S transponder.
See
.
TIS In/NMEA & VHF Out—receives TIS data and transmits
out both NMEA data, at 9600 baud, and VHF frequency tuning

If you select GARMIN DGPS or RTCM In/NMEA Out format,
you can control a differential beacon receiver directly from your
GPSMAP 495 using the Interface sub tab. You can have the unit
automatically scan for the DGPS beacon signal, or you can enter
the beacon frequency and bit rate on the unit, and the information is
used to tune the beacon receiver. If you use a DGPS receiver, WAAS
capability is automatically turned off.
