case, 2906F250 is the Station ID.
Towed (Still)
After you press the “Park” key, while the carrier’s position is away from its parking
space over 100m, G-19B will auto report “towed” message to the first predefined
phone number, PH-01; otherwise it will report “still”.
Move 450m NE
This segment indicates the movement of G-19B.
G-19B will calculate the distance between the original position of your car and
current position to show the moved distance and on-going direction.
Now(Previously 17:26)
This segment indicates GPS data validity of G-19B.
If this segment is “Now”, it indicates GPS fix is in real time.
If this segment is in 24 hour time format such as “Previously 17:26”, it
indicates G-19B currently cannot receive enough GPS signal to fix position so
as to send the last GPRMC data at that time (it will be transformed to local
time directly).
$GPRMC
