Ray,
I think there is a small mistake in your coordinates as I assume that there should be no dot after 4500 in the Lat: 16.4500.59
If I delete that second dot and set the GPS to ddd.dddddd (decimal degrees) the coordinates Lat 16.450050 and Long 102.817397 put me in Khon Kaen a bit north of the Khon Kaen University Kanchanaphisek Convention Center.
