First I really like my TM-D710A radio. It works great, never gives me any problems, and I use it daily. The main reason I worked diligently on the AVR APRS display was to have a screen and keyboard attached to radio out in the field. The TM-D710A works well for short messages but it could be so much easier with a keyboard. I've started work on building a keyboard interface for a small rollup keyboard. I'll post progress here but I'd like to know if there is more interest in this project out there. If so leave me a comment or drop me a line.
