TomTom has been pretty good for me. Not infallible, though, but then none of them are.</p> At times she has led me astray........but then all exciting women do. She tried to take me into a field in Cawthorne the other day. Cheeky mare </p>
Agreed I find it helpful to play the route through in demo mode before travelling if I can. That way I can visualise where it's trying to take me from what I saw on screen. They're not infallible though so also have a look on a map too. Maps are good but you can't read & drive at the same time, not legally at least. SatNavs are also good but aren't always up to date with the latest streets. I had a friend's TomTom try & take me the wrong way up 4 consecutive one way streets once!
