4.2.12 Programmable Device ID (PGRMID)
The Garmin Proprietary sentence $PGRMID gives the device owner the flexibility of naming each sensor device
with a custom text value.
$PGRMID,<1>,<2>,<3>*hh<CR><LF>
<1> ID Configuration Command, S = Set ID, C = Clear ID, E = Echo ID

<3> Garmin Unit ID (Predefined and unique to each device)
4.2.13 Map Datum (PGRMM)
The Garmin Proprietary sentence $PGRMM gives the name of the map datum currently in use by the GPS sensor.
This information is used by the Garmin MapSource real-time plotting application.
$PGRMM,<1>*hh<CR><LF>
<1> Name of map datum currently in use (variable length field, for example., “WGS 84”)
4.2.14 Sensor Status Information (PGRMT)
The Garmin Proprietary sentence $PGRMT gives information concerning the status of the GPS sensor. This
sentence is transmitted once per minute regardless of the selected baud rate.
