Might be mention where you are and firmware would be helpful? is map preloaded?

I'm in Los Angeles tried the Drive the first time yesterday and I got the phone only the day before. Updated to the latest PR1.1.

I love the Drive app. No problem at all, easier to use than the Google Map/Navigation on Android. Very fast to lock on my location and because the map (California) was preloaded, it is very smooth over all. A vast improvement over the half baked Map on N900.

It did freeze once when I click on the Start button to start navigation, it prompted me to kill a processor which was not responding. I killed that and restarted the Drive and it worked well again.
