None of the manufacturers can get it right. The radios that have an onboard GPS cannot be seen by APRS programs so you have to attach a separate GPS. I had a D72A and sold it thinking Kenwood鈥檚 new Tribander D74 would do the job. The biggest drawback was the D74 is D-Star and not C4FM. Guess Icom has more pull with Kenwood than Yaesu at this date. I am waiting for a radio that will never be built that will allow the APRS program to use the GPS in the radio and also has C4FM. I went back to my D7(g) and an external GPS. I sold the D72A before prices fell due to the D74 coming out.
I have for 15 or more years tried to get an APRS HT with maps and messaging on a screen. I now have all the components and turn n the 3D printer to house all the components. Use a Winbook, UI-View, D7(g), GPS, and Weego battery pack.
In the old days I had this setup using a Dell Axim X3 PDA, APRSCE/APRSGO, and a external GPS. Maps were the only issue with the APRSCE program back them and the author got burnt out updating the program; was pending using OSM Maps.
A APRS HT like this could be handed out by FEMA during catastrophic events. If the TNC buffer were large enough, this unit could also do Packet/Winlink Express also. What a tool to have in support of emergency radio.

Geez Steve,
Don't talk like that on a Yaesu group or you'll be stoned to deatha blasphemer.
Many moons ago while we were waiting between the D7A(g) and the D72a, Yaesu came out with the VX8R. I pointed out the shortcomingsof that rig setup and the closed TNC and those Yaesu fanboys had a conniption. Besides the KW shortcomings you point out, I believeKW "did it right" much better than Yaesu. Though the FTM has a fancy dancy color display the OP will have to decide whether or not he "really" wants the Fusion stuff and live with the hobbledAPRS performance or go with a KW with the more plain Janedisplay (but better APRS capability).

if anyone is using this radio with UIVIEW and what settings they are using on
UIVIEW.
I thought I might want to add the fusion digital seeing I have DSTAR and DMR
already.
Thanks!

This radio, along with many other Yaesu APRS radios, shares what I consider a
fatal design flaw for APRS operation. It works fine in standalone APRS
operation, but unlike the Kenwood APRS radios, does NOT offer full and
unfettered access to it's internal TNC from external devices and computers. A
basic ASCII receive monitor stream is available from the radio's, COM port
--but-- there is NO ability to TRANSMIT anything on APRS from an external
computer.
This reduces UIview to only a passive receive-only monitoring/mapping mode.
There is no way to do messaging (which obviously requires TX). There is no way
to transmit objects. (The radio's internal APRS functions can transmit your own
position.) Due to the lack of transmit and KISS mode, UIview definitely cannot
use it's digipeater or two-way igate functions.
Since the internal GPS does not echo it's readings out the COM port to , you
will have to use a second EXTERNAL GPS receiver connected directly to the PC
with UIview. [This is a maddening limitation shared with the Kenwood APRS
radios. The Kenwood D710 and D72 will pass the GPS data from an EXTERNAL GPS
receiver connected to the radio out the radio's main com port along with
received APRS data. They WILL NOT echo out data from the INTERNAL GPS device.]
