Alright I now that I've got my new radio installed I'm wanting to play with APRS a bit. And it got me to thinking. I know parts of APRS relies on GPS input. That left me with a wondering, is there any way to hook your GPS enabled smart phone into my D710A and utilize that piece of tech to it's fullest? It would be nice if I could but obviously this was not a thought in the design process of this radio. Outside of that what are some good Garmin options?
