Hope I'm not asking a question that I should have easily been able to find. Looked, and thus far, have not. I'm going on a road trip next week. Live in Tampa and traveling to Baton Rouge. Have a 2011 GS350. Would like to map out a route to my destination with a few stops along the way. Does the nav system allow for me to map out my route and save it... in advance? Instead of waiting to get on the road and then program...

TIA
Toni
