     2 if the data is valid and fresh
 
+  If the module is using multiple GNSS constellations, the GGA message will be prefixed with Talker ID "GN" instead of "GP".
+  The library includes a getLatestNMEAGNGGA function too.
+  This example shows how to use both functions - and how to change the Talker ID so the GNGGA messages become GPGGA.
+
   This example turns off all sentences except for GPGGA.
 
   Feel like supporting open source hardware?
