I use a Mobilinkd TNC connected to a Yaesu FTM-3100. I liked the bluetooth between the TNC and the tablet so I didn't have to run any more cables around/through the dash.@prerunner1982 just stumbled across your post after playing around with APRSDroid. Been having some difficulties with the Argent Data Systems Tracker4 TNC but have APRSDroid working on for now.
Was wondering what setup you have for your APRS in the vehicle apart from using APRSDroid on your phone. Thanks!
