You still need to question them though, at least I do.
I don't tend to have a great need for one but I have used them and probably 99% of the time they have been great but every now and again, I think what they are telling me can't be right.
A couple of years back I used one to drive from New York to Toronto - no problem going there but coming back the sat nav wanted for some reason or other, send me about 300 miles out of my way!?
I literally saw a sign saying New York 175 miles and the sat nav was telling me almost 500!
Obviously I didn't know the roads over there but if you've ever been to the states every road - even minor ones - seem to be as big as our motorways and have next to nothing on them.
I followed my instincts rather than the sat nav and had no problems at all getting back (it recalculated after a few miles anyway to something very much closer to what the sign had said).
Sat navs are indeed very good but not always 100% perfect imo.
