there's one road on the way to the Panshangar course where it thinks there are about a dozen right hand turns, none of which you want, in 300 yards. actually there are none and when it gets to the turning you do want it's taken by surprise and misses it.

I think you're right though, TomTom seems to be the only one that updates right through the range.

Pity I didn't title this post as Don't buy Navman, that way it would show up in a Google search.
