you are correct 45 seconds to lock is a long time- that is how long it just took in my office.

it does not take longer than 45sec-1min if you use agps properly:

1. open agps while connected to the internet( make sure that in the settings a-gps support is checked off and allow packet data is checked off.

2. locate your position on the map. move the red dot to where you are located.

3. allow the agps to download the satellite info (depending on the speed of your connection - it can be as short as 1 min. when i fly before i leave i set my destination on the map and set agps do it stuff while i am home on my fast wifi connection.

4. CLOSE AGPS

5. open map or maemomapper (your choice) and you WILL have a connection w/i 1 min
