I went for a drive with a friend in his car which had a built in sat nav so I took my Tomtom
along to compare the two, and they argued all the way, lovely Alice in the Tomtom and some American dude in the other, turn left, turn right they didn't agree once, it was like kids squabbling.

Any one else had problems with sat navs and has Turkey been mapped for sat navs or is it a military no no.
