DGPS corrections are accepted in RTCM-104 v. 2.0 format
through the NMEA In (BROWN) harness lead. The GARMIN GBR 21
is the recommended beacon receiver for use with the GPSMAP sys-
tem. Other receivers with the correct RTCM format may be used, but
may not correctly display status or allow tuning control from the
GPSMAP 195 unit. When using the GARMIN GBR 21, select the
‘RTCM In/NMEA Out’ interface format (as described on page 74).
Other differential receivers may use this setting or the ‘RTMC In/No
Out’ format.
