I do look up routes before I leave and I do print maps and written destructions ..... but there are times when I just follow the car in front until a sign appears. I'm not that good at map reading if I'm honest.
We came across ( not literally ) one of those multi mini roundabout thingies in Colchester last year. Hells bells!
We don't have stuff like that oop North.
We have a large screen satnav built into the dash, it comes on with the radio. I like following the maps as we drive along but don't use it for direction finding. I don't need any lip from the car! push-up
