Hi!
You can use online NMEA decoders to see where does that "parsed" message lead you
In this website insert your GPGGA data ( $GPGGA,212533.00,5314.932656,N,00639.524180,W,1,08,0.7,95.4,M,48.0,M,,*49 ) ant just look for a difference with the MAP FIX you got in WebUI, in this scenario:
You can insert this latitude and longitude info in Google MAPS and it will indeed show you the same place you checked with NMEA decoder before.
