I have almost given up on my NuVi because, like you, we like back roads and not interstates. With the Garmin if you say avoid them, it will route you through some ridiculous roads to avoid even a small section of interstate. It is either on or off, not prefer. And, it will not give up...it insists you take that route. Just my opinion and a data point. Others will disagree.
So what GPS do you use then, that allows back roads routing with "some" interstate?
Have you tried Google Maps via voice command? Like this:
Okay Google directions to XYZ avoid Interstate 80
That has worked for me in the past, telling it to avoid a major road.
I like how ancient Microsoft Streets gives you sliders, from strongly avoid to strongly prefer for different road types. Not just all or nothing.
