Make sure you have told the radio if you are or are
not using a GPS depending on your particular setup. 
It won't show any received packets or keep the list up
to date of received data/stations unless you tell it
how it is supposed to work.  I don't know what the
menu setting is but its on the APRS menu, 3 I think,
but I don't have the submenu numbers.  Also, another
menu setting has to be set to what NMEA string to
expect from the GPS.  If that isn't right, then it
won't work either.
