A ham that I know has a mobile ham radio with APRS in his car. He has this plugged into a GPS on his dashboard. What he is then able to view is where the different hams are on his GPS map. My question is can the same be done with the Kenwood TH-D72 as far as plugging it into a GPS and being able to view other people that have there beacon on the map on the GPS. Yes I realize that the kenwood has the GPS built into it but it does not have a map that i can see where everyone else is. If this is possible what do i need to do so. What kind of GPS would work for this? Thank You in advance for your help.
