GPS for leisure cycling including cycle routes through towns

I am an OAP as well as needing glasses to read by. My electric cycle is fabulous but in my town we have off road (estate) cyclepaths. I have been using a Nuvi 1490 but cannot set up routes from waypoints. It comes out on Basecamp as a spiders web - trying to use the roads. Would a dedicated cycle GPS be any better? Or are they too small to read?
