Just that really.
After another horrific journey where I had to reverse for about a mile as there was no passing place I’m feeling pretty traumatised. 
I live in South Norfolk and we have a lot of very narrow one lane country roads and I have a new Kia with built in sat nav - without fail every time I use it it takes me down the most obscure routes, often turning off a lovely A road to take me down a 3 mile stretch of dirt road only to rejoin the same A road later on…!
Obviously I do check the route beforehand but sometimes I get pretty lost, I’m human.
There is a setting to avoid motorways but no setting I can see to stick to A roads and main roads! Am i missing a trick?
Is there a way to do this or does anyone have an amazing sat nav / app that allows me to do this?!
