MRA and tunnels
-
Hi !
In just 29 days I leave from Romania to the Swiss Alps and I am wondering how does MRA behave in tunnels (and I have to pass a lot in Austria) ?
I want to use the track record function as well, and I was wondering if it works well trough long tunnels, where there is no GPS signal ?
Thanks !Best regards,

Thanks !@Adrian-Avram I would for obvious reasons avoid positioning route points inside a tunnel and I would also avoid positioning them too close to the exit of a tunnel, the app will need to wake up and get a fix on the satellites again. As the tracking works from the GPS signal, I suspect that you'll see straight lines for the tunnels.

mra recovers after leaving the tunnel, but inside the tunnel it behaves chaotic. it sometimes thinks that you are driving backwards, recalculates accordingly , severely effecting the ETA info.
I have a video showing it if you are interested.
Tomtom behaves better, i guess it assumes that you drive at constant speed and moves the cursor accordingly. -

I experienced the same in a Stockholm tunnel recently. It was a bad experience, because I had to take an in-tunnel exit, and since the map didn't keep updating my assumed position, it was hard to know which exit to take.
So Adrian, you need to look carefully at the map prior to entering a tunnel, so you know if you have to take an in-tunnel exit.
Best regards, Makro

@Makro thats what I am afraid of. Thank you for the advice !

Swiss Alps? Don't forget to disable roaming on your telephone. When not, you're in for a surprise when you will receive your telephone bill.

That entirely depends on what kind of data cap you have with your provider! I don't worry at all
