Routes Question/Nuvi 2595

Hello All,

So I've got a route that I created in google maps. I have it imported into basecamp. I'd like to send it to my GPS. Which it appears like I can do. And have done. When I disconnect the GPS from my PC where do I find the route that I sent over to it?

And once I reconnect it appears as if the file is gone. What am I missing or does my GPS not support this feature.

The reason I ask all of this is because I have a custom route I want to take when I travel to the beach this up coming weekend.

Any help is greatly appreciated.

Jesse
