Review on 📺 Enhance Navigation with Rand McNally 7-Inches GPS Anti-Glare Screen Protector by Michelle Rogers

I got this and my tnd 730 at the same time. I put it in as soon as I took the 730 out of the box. When I charged my device and tried to get it working none of the buttons worked so I called Rand McNally thinking I'd just ruined our lives and spent $350 on a junk GPS. They really had nothing to say to me, so I started playing around with the device and realizing what I was losing if I removed the screen protector. Second, I aligned the sky and my GPS worked great. Now I like my tnd 730 but would like to do something to protect the screen without sacrificing functionality.
