I'm not equipped GARMIN, I have a MIO SPIRIT 480 and this device fits neatly on this one. This visor is not flush on GPS but simply laying on and fixed with the clamp. The window is 6.5 cm by 11 cm. You decide if it suits your GPS. It has a very nice shape and perfectly complements your gear. Please do not deprive themselves of enhanced playback. N "please and enjoy your trip (s)
