I turn on my device, but it will not locate my position.

Your GPS might need some time to connect to the satellite in order to get a proper signal. Also, your GPS will have trouble with location if there is not a clear connection path to the satellite; for example, parking garages and tunnels could be a reason.

for my garmin nuvi 65LM - while driving the GPS always Lost Satellite Reception, signals come & go..  Already did hard reset but problem stays the same.
