I'm not a fan of Sat Nav systems - give me a real map any day of the

Naturally local knowledge will always beat a computer, but Sat Navs
come up trumps when you visit a place you've never been to before.

To my surprise, my satnav has occasionally also found better local
routes than I had.

But it sometimes also gets it wrong due to errors in its maps or its
ignorance of the fact that some minor roads are actually quicker than
parallel major roads. It also doesn't know about width restrictions --
my car only just squeezes through 6' 6" restrictions, so I try to avoid
them. However, I am able to program in areas to avoid, so it's getting
better.
