I now have APRS installed in my truck. I put a NMO 1/4 wave antenna on the headache rack. I also installed a 3 socket accessory block, needed to plug the new items into. The display tablet is an HP8 mounted with a Lido seat rail mount. I put the tablet in vertically ,as you would normally use it, and it fits a works fine. I would like to update this with a 10″ tablet in the future, easier to see the screen. Everything seems to work very good together. I will have to say that the Mobilinkd is a good way to get started in APRS.
