I never really cared to mess with the stereo. It sounds/works fine for me. However, my buddy developed a cool app that uses gps and HAM frequencies to track and locate people. It's like the Garmin mapping app, except you can find people when you don't have cell reception, as long as you're in HAM radio range. Anyway, it would be awesome to have that tracking app running on a nice, clean, built in screen. So, that's why I went down this road. I'm bummed it's not working out. But, I'll just go back to my tablet hanging on a bracket. Not as pretty, but, at least it does hiss!!
