Problem of GPS for the first time

i found allot of my friends with N95 having problems running the GPS for the first time
i found that for the first time you have to run Tools --> GPS data in a wide area for about 10-30 mins
till you got a connection then it will be easy to run it again
but take care it may not run in homes and car and the time till it connect depends on the area you are in
some times take 20 secs and some times takes 5 min
