I recently installed the Garmin Zumo 660 on my Trophy and was very happy with it except for one thing. The screen seemed washed out in bright sunlight. I looked at several sun shades on line but some of the reviews made me hesitant to buy them. This past weekend I made my own sun shade and it came out fairly well. I was out riding this morning at it worked very well. There are still certain situations where the glare is bothersome, e.g., when the sun is directly in back of me. I have attached a quick plan of how I made the sun shade. I do have to thank my better half for the help with sewing the sun shade!
Cheers
