In general i get GPS fix on my cameras pretty fast, but there are also days where i am thinking " to hell with those American GPS satellites, lets get some Galileo ( EU GPS system ) support for dashcams".
Not least my K2S system, which announce GPS aqusition in a voice, some times i can get pretty far from home before i hear that announcement, and other days it is followed in seconds by GPS signal lost,,,,,, only to be there again in a few seconds ( but those are rare and always within the start of a drive )
