Google Maps to Base camp to 60CSx, Nuvi 550 Help

I recently created a motorcycle route using Google Maps. I was able to export it to Base Camp and create a route. Now, when I try and send the route to my GPS (tried with both 60CSx and Nuvi 550, I only get part of the route. I've tried removing shaping points. I've changed the number of via points exported and nothing is working. I've searched the forum and not found much that is helping. I am using Base Camp 4.3.3.

Can anyone offer some advice?

Thanks.
