Tom Tom, Sav Nav, Bah.
You'd be lucky to get a phone signal in some parts of Wales.
Bring plenty of bread crumbs
Or a long bit of string.
When I went to Colchester to buy the Alfa the guy asked me "did you bring a sat nav or map?" to this I replied "no" then he said "how are going to find your way home?" As I had gone by train and then he picked me up from the train station.
I looked up for the sun and asked him what time it was and then said.."I live over there" Got in the car and drove off....
