Magnetic Phone Holder Support

This is a Holder for a magnetic phone mount, that keeps it in the Landscape position for GPS and what not. I was tired of my phone turning on the mount, everytime I hit a bump, then having to readjust it. Since, my phone is in a case, the metal plate is behind it...which makes the magnetic field weaker. I also didnt want to hinder the speed of putting a phone in a magnetic mount, so this was my solution. Couldnt find anything else on here that would do the same in Landscape mode, all the others
