Compatible with Garmin 492?

[PDA1]

Is a Garnin 492 GPSMAP compatible with OpenCPN?

I'd like to be able to import and export routes.

Here's what the manual says;

The following are the sentences for NMEA 0183, vs. 3.01 output:

The following formats are supported for connection of external
devices:
Approved sentences—GPRMC, GPRMB, GPGGA, GPGSA,
GPGSV, GPGLL, GPBOD, GPBWC, GPVTG, GPRTE, GPXTE,
GPWPL, SDDBT, SDDPT, SDMTW, SDVHW, and GPAPB.


Proprietary sentences—PGRME, PGRMM, and PGRMZ. The
GPSMAP 392/398/492/498 accepts NMEA input with support for
the DBT, DPT, MTW, VHW, and WPL sentences.
