i have a sat nav purely for the detour button!.
id rather drive 100 miles out of my way than sit in a traffic jam for an hour!
(plus i cant read arabic or russian road signs!)
I've never had the Foz abraod yet, can't say I fancy it much. Always lrefer to hire one with t wheel ont 'right' side of the car for the country I'm in...
Always prefer a map plus traffic updates on FM for UK driving, and Google Maps with it's traffic function on the iphone for when I near major conurbations.
There's something factual in a map. It tells what what there is, as opposed to telling you where to go. I never like being told where to go.... (cue abuse from mdg, NDS et al)
