Most of my experience is with NAVTEQ, who many say is the better provider in North America, but..

From what I can find - which, surprisingly, isn't as much as I'd like - TeleAtlas is the better data provider in Europe.

So far, except for a slimmer POI database than I'm used to - but it's always hit or miss - the TeleAtlas map seems to be somewhat more accurate on actual "road positions" but somewhat less accurate on their address model.

But why would choosing TeleAtlas be "the wrong one?" Sorry, I'm only trying to learn more about this.

I won't hide the fact that I was VERY leery at first, but as I've gotten to use it more - the ETA issue I described notwithstanding - I've actually become IMPRESSED. Maybe it's just the graphics, but it's been very satisfying to use. A bit slower than I would have thought for a hard drive-based system, although not any worse than the DVD one I was used to.

Oh, and that startup time still kills me. The ancient Lexus DVD-based system was "instant on."

We've had a major off-ramp get closed and two major highways about to come online (extensions, really) in the next year or so, so I'll wait for another update.

In the meantime, I know BMW said recently they were going to go to the MeeGo environment going forward. Not sure if THAT'S a good move either.
