yeah, I got a N95.
Need to be outside (obviously) and expose the keypad.
Initial aquisition of the satellites will take any where from 3 to 15 minutes.
That's quite normal for hand held portable GPSs. It might be possible to tell it where it is so it knows which bit of the sky to look for satellites in.

Paying for the track following is exy too.
I just use it to locate where I am in the city and then set off.
