I did create a few waypoints on the gps on the ride there but for a complex route
where I specifically want to try certain roads, creating the route in google is better and much faster for me.
You can skip basecamp but then you'll only have a track and not a route. I like using routes so you get prompts and then setup the gps to not recalculate. Also using Basecamp ensures the route is right on the CNNA map.
Navigon on my iphone has neat way of routing. It will give you three route options, fastest, shortest and scenic. I wish the Montana would do this.
I use this sometimes for ideas. Walking directions is also a great way to get ideas in google maps. I always start with that.
