2015 GMC Sierra Navagation system

[Toolguy5]

Just took delivery of a 2015 GMC Sierra with Navigation system. In the settings for Routing there is something called ECO profile routing. It has a roof load and a trailer load. Settings are none, small, medium and large. Then select ECO friendly route.
If I set this to large will it be like the Rhand McNally 7710 where it will keep you on routes that you don't have to worry about narrow roads, low bridges etc.

The tech guy at dealer did not know.

Does any one have experience with these.

I believe the eco route is a route with less hills and elevation changes to get you better fuel mileage from your truck

Sometimes the simple things in life are best. $15.00 Motor Carrier Road Atlas for truckers. Not saying technology isn't great, but you have to have a Philly lawyer to tell you how things work.

I have looked in all manuals. Watched many YouTube videos. Can't seem to locate anything.
I will try and have a live chat with GM today.
Thought I would see if anyone on forum has used this feature.
