First of all, only Band A (left side) can be tuned to the aviation band; if you try to use Band B it will not work. Press the left "BAND SEL" button (volume knob). Then you should be able to use the tuning knob to tune to the frequency you want.
If it skips over the aviation band, then the first thing to check is that the aviation band is not masked. This ...
I am setting up a B2000, a TH-D72 and a 710GA.
The best practice is to set the APRS freq to 144.39 MHz in Band B then configure the data band of the TNC to B-Band. You can lock it as well.
Kenwood has "In Depth" Manuals for each model for APRS.
For this I use an RT Systems USB-K5G cable connected to the COM port on the back of the control head. On my laptop I'm running Pinpoint APRS v2.0.

601 INTERNAL TNC:
DATA BAND: B-BAND
DATA SPEED: 1200 bps
DCD SENSE: D or RxD BAND
TX DELAY: 200 ms
602 GPS PORT:
BAUD RATE: 9600 bps
I'm not quite sure why things worked in today's testing, possibly I was just in a dead zone yesterday. Here's the setup that's working though:
DRA-50 is plugged into radio's "Data" port (on main body) and into laptop. This is the port for using an external TNC, which is indicated by a plain 'D' next to the power level indicator on whichever band it'...
I never saw a viable answer here. Realize this post is a year old, hopefully it is answered somewhere.
The solution is to select band A, left side by pressing the left volume control on the right side of the display. Then press F, followed by pressing the left volume control button. I'm not sure how to do this repeatedly but what I did was press F then ...
I don't own a D710 myself, but I was looking at buying one, so this is from my understanding of the manual: no, the D710 does not have a dedicated APRS VFO. If you look at page PACKET-2 of the D710 manual, it describes selecting which "band" (A or B) is used as the data band.
This fellow mentions that he planned to do this:
Install serial cable from TM-D710G in basement to office for a future project - computer control over radio frequency, etc.
But he may never have been successful. I do not see the TM-D710G listed in any of the transceiver control software lists:
Commander doesn't list
Ham Radio Deluxe doesn't list
