You don't need a gps or smart phone to plan and follow a route. All you need are decent local maps. Get in advance or as you go.

I enjoy using Google map service to plan a route. I have transferred that to paper maps which I trimmed and taped together into a managable and convenient size. A gps is a luxury and can mislead you if not used cautiously. I do use one.

All you need to know about touring are at the links Ray referenced. Good luck and have fun.
