I think what the problem is, that as an ex International Trucker, I know my way around Europe quite well and I am proficient at map reading.
I am trying to convince myself that I need a Sat Nav for the last mile into Aire's. Don't know if I really do and as you will know, sometimes you drop on the best places purely by accident!
I am going to France in very high season this year and everywhere will be chocker blocked. I thought the Sat Nav may help and that is the only reason.
But can I justify the cost?
