Glad it's working for folks. A few responses:

Good point, Gary! - I'll add yours bits to the main post if that's ok with you
To the comments about CW routes, I do think that's correct - remember, I found that there is web-based management of routes for the CW routing solution where as Google only sends destinations. When you enter a destination from your Leaf, it does a Carwings check (which I believe is for traffic) before having the NAV route you. I wonder if the CW routes really are just multiple points (an origin, intermediary stops as application, and a destination) vs. the Google Maps simply being a single destination.
I guess bottom line I'm saying that I bet the Nav system is always doing the routing - and that the only think going back and forth between Carwings in the car and the Carwings server are addresses/points... multiple in the case of their routing service, single in the case of google maps.
