Infomap Navigator on the hand is a bit ****e, and gets me lost all the time, I need some decent GPS software.
I agree...according to the seller he used it all around europe and never had a single problem. I took it for a test drive which involve 10-15 maneuvers around my area. I deliberately confused it...heck it want me to go around 100 miles from where I wanna go...how ****e can it be
Theres many different type of lock...all depend how you started off at the first place.
For example Garmin GPS16 lock as follows :
Reacquisition: Less than 2 seconds
Warm: Approximately 15 seconds
Cold: Approximately 45 seconds
AutoLocateŽ: 5 minutes
SkySearch: 5 minutes
But lock do just generally means the time it take for the GPS unit to calculate its location from switching on...
as DodgeCummins said. It need 3 or more satellite to lock on for it to do a 3D calculations.
