It takes a while to locate GPS - but I'm in a building...
It takes longer than Blackberry Maps does...
I would never compare GMM w/ VZNav... They aren't competitors. GMM can do directions, but it's not made explicitly for that function (maybe future versions will be).
I usually don't drive anywhere I need directions anyways...
I get 3.0.2 to do GPS - within 100M inside my workplace.
I think Google is still trying to use A-GPS first, then when it times out (because Verizon isn't providing A-GPS to anyone outside of themselves), they go to S-GPS.
Probably why it takes longer to get connection.
I could see Latitude as being very cool if you're on a trip as it would allow people at your destination to see where you are - especially if they need to give you directions!
