How do opencycle look on gps?

I been looking for a good map of the bicycle paths for Holland. I have download the “shsh” $100 Onroute and all the free one. Onroute to me is just a single map of Holland. It only good to tell me where the food and beer pubs are. I came across the Opencycle on the web and it the best one I saw yet on the web. I am thinking buying a Garmin nuvi 500 3.5 to do this trip. If the trip is a go I would like to connect the dot and don’t care about anything else. Holland is flat.

Do anyone know how it look on a gps screen 3.5 ? Is is clean looking like the phone app ad.

Have you tried openfietsmap Benelux?
