No
—
The radio does not send position information even if position
requests are received.
•
Priority calls only
—
The radio attempts to send position
information only when position requests from authorised
numbers are received during a call to an emergency number
programmed into your radio, or during a
red key call or a silent
red key call to a network mode destination. If the GPS receiver
does not get the needed information from the satellites to
determine the current coordinates before the call ends, the
coordinates that were last calculated by the receiver are sent
instead.
Note that position information from the GPS receiver may be sent
to the network during these calls if it has been predefined by your
organisation, regardless of which setting is selected.
NMEA interface
If the radio is connected to a compatible PC with a data cable, you
can send position information to compatible map applications on the
PC. The protocol NMEA-0183 version 3.0 is used for data transfer.
To activate or deactivate the GPS receiver and the sending of
position information to the compatible PC, select
NMEA interface →
On or Off . When NMEA interface is On , ( ) is shown on the
display.
Approved NMEA sentences include GPRMC, GPVTG, GPGGA,
GPGLL, GPGSA, and GPGSV. The default data transfer rate of the
NMEA interface is 4800 b/s. AT commands cannot be used when
NMEA data transfer is active.
