This is a GPS SunShade. This SunShade is made by Vizon-X and is designed to keep the glare off of your navigation system on those bright sunny riding days. It is made of black ABS plastic and is felt lined to absorb the glare from the sun. Their patented design is custom made for the Garmin Zumo 660 and 665 GPS models. The top extends 3 1/2 inches for great protection from the sunlight and it attaches easily with velcro on the rear tabs on the unit.
