well, it takes me about 30 minutes to get home from work, on a 50-60kmh lakeside road. When I get out of office I turn the system on and go to map (I like to see where I am on the road, it's kind of fun
). And usually the map is correct, even if I do not have a 2D/3D fix, I see the map showing my position correctly. But then I turn of the main road just 20 meters (because of construction work) and NAV looses my coordinates and never regains them till I get home (about 15-20 minutes).
OR it could be that I have no lock when I get out of office, but then I have 2D lock (2-3-4 sattelites) but the system does not adjust my position, and I am driving over the water.
How come it is so slow?! My portable Nüvi is much faster to adjust.
Also funny thing, when I go from Zurich to work I usually have better luck with satellites than when I go from work home, on same road.
I think maybe it is the position of the antenna. I want to see how the garage fixed it inside the vent.
Or do you guys think it could be something else?
