I just started to use the Garmin Route Planning feature of Base Camp.I have two planned and saved to my nuvi50. I planned a third, allowed it to route the trip, then I attempted to load it to my 50. It didn't load. I believe I used the same process & I'm connected with a USB cable. To much data? And why isn't there a progress bar when migrating trips from the Base Camp to the device?
You can send hundreds of routes to your nuvi. If there was no progress bar it's not being sent but one route will go quite quickly so you may have missed it. It may take a while to import into the trip planner app of your nuvi though so perhaps you didn't give it sufficient time?
