I love this app, been showing it to all that will listen. So nice being able to see the larger screen of a smartphone (using the mil spec Rugby Smart). Hold phone to Ram mount with heavy duty velcro and got stick on (automotive-grade adhesive) loop to attach a tether (dang phone doesn't have one). Hard wired a fused 12V outlet for the branded higher amp charger. All stuff I learned right here, cept maybe the tether loop I found myself.
