You can do custom routes on the device, choose the route on a map, make notes,
Set the destination on the garmin and let it build a route,ideally a days riding,
Touch the screen and it goes to 2 D ,zoom out and view the route,
Find the roads you prefer and touch the screen at that point to create a via point,
It does involve zooming in and out a bit and you can move the via before setting,
Add it to current route it will re calculate and check by touching the screen again,and zoom out,
You are then able to add others to bend it where you want or return to drive it,
Avoid via points at junctions and zoom in to make sure its on a road,
Using avoid preferences like tolls, motorways, and routing , faster curvy, shortest to
enhance the initial routing, you can change these at any time, but re check the route
When you get confident, adding vias from the poi menu for fuel and interesting places etc makes a comprehensive trip, when you have finished iether turn the garmin off or drive the route,
you can also save the trip as a route when at destination with trip log enabled,
This is my preferred choice for trips as it does a lot for you and often throws in some interesting roads, above all its quick and easy,,and flexible,,
This is one of many option for routing , and ideal for a beginner,
once mastered base camp is good,
Have a great trip,,
