The GPSMAP 695/696 is compatible with the GDL 39 data link radio.  The GDL 39 

is a receive-only data link radio with on-board GPS, 978 MHz (the Universal Access 
Transceiver frequency band), and 1090 MHz Extended Squitter (1090 ES) receivers.  It 
is designed to receive, process, and output traffic (ADS-B air-to-air, and TIS-B traffic 
information), and weather (Flight Information Service-Broadcast (FIS-B)) information 
to the GPSMAP 695/696 through a power/data cable.  As a UAT receiver, the GDL 39 
can receive and, when connected to the GPSMAP 695/696, display Flight Information 
Service-Broadcast (FIS-B) weather products as well as traffic. 

FIS-B is a free weather service that is broadcast by Ground Based Transceivers 

(GBTs) over the 978 MHz UAT frequency band as part of the FAA’s Next Generation 
Air Transportation System (NextGen).  To receive FIS-B weather information, the GDL 
39 must be within range and line-of-sight of an operating GBT.  Reception may be 
affected by altitude, terrain, and other factors.  GDL 39-supported FIS-B weather 
products include METARs, TAFs, NEXRAD (Regional and CONUS (Combined)), AIRMETs, 
SIGMETs, PIREPs, and Winds and Temperatures Aloft.  Other products include NOTAMs 
and TFRs.
