CFG1 NMEA Out screens for the identifier given below. The CDU
outputs these sentences in the following format:

Rnn - Routes:

Waypoint identifiers, listed in order with starting waypoint first, for
route number "nn". The active route in the CDU is always route zero,
but in the Rnn sentence the route number can be transmitted as ei-
ther route 00 or 01.
Rnn is NMEA version 1.5. Use of GPRTE is recommended to com-
ply with NMEA version 2.1.

RTE - Active Route:

Waypoint identifiers, listed in order with starting waypoint first, for
the identified route. Two modes of transmission are provided: "c"
indicates that the complete list of waypoints in the route are being
transmitted; "w" indicates a working route (active) where the first
listed waypoint is always the last waypoint that has been reached
(FROM), while the second listed waypoint is always the waypoint
that you are currently heading toward (TO). The remaining list of
waypoints represents the remainder of the route.
RTE can be sent as version 2.1 and 2.0.
