On a recent trip to Switzerland, two months ago, came of the ferry at Dunkirk, Sat Nav , decided it was still in the carpark in Dover, took it about 15 miutes for it to get its bearings, luckily I knew where we were. Its the road numbers that get you, district, National and European, the same road could be the D116, N18 and the E 47. But all roads go to Paris. We worth getting a Sanef tolling, tag. Pay at the end of the month. For Paege.
