Indicator arrow drifts all over the map.

[M. Schrijver]

Most scenic route tunnels don't have fallback for GPS and cellphone.
Tunnels are normally known on the maps. And it is known GPS signal is gone in tunnels. So the software must take over. Every software has it own way of doing this. Mostly the software expects you drive at a constant speed through a tunnel and after leaving the tunnel (according to the map) they stay on this course for a while. In the mean time, the software tries to find the GPS signal again and links to the GPS again for a more accurate postion.

Now back and had no drifting arrow. as said before i had an arrow that in 25% of the time was behind. i did test today on other app and no problems. if it was behind i had to restart the app.
i use offline and no recalculation.

an other thing that seems not to work is starting a track in offline mode.

I have the same problems with the "arrow behind" case. Well not only arrow but also the navigation itself.
"In 400 meters turn right", a split second later "turn right now"...

when it is behind i get message on the crossing so to late. but as i said it is not always behind. also i have no other gps apps running and also no tracking.

This lagging is also visible in the tracklog. Less trackpoints and thus more straight lines.
