I hate the fingerprint marks and smudges, that I was putting all over my system. So I found a handy little item at Walgreens for $5.00 and it works great. I bought one for each door, so Renee and I had our own to operate the Infotainment System. It's called the Stylus, the tip is soft rubber and keeps your screen free from scratches and fingerprints. I'm more accurate when I select anything on the screen now than before. "Point of aim, point of impact"
