The last thing you want when you're using your GPS is to be unable to see the map on screen. While the HX-1's inbuilt turn-by-turn guidance system is great at communicating upcoming turns, it's always useful to have a constant visual reminder, which is exactly where the HX-1 Sun Visor comes in. Easily fixed to the top of your HX-1 with two rubber coated springs, regaining full visibility is right around the corner.
