MRA and 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.@Herman-Veldhuizen yes, can you put a link to the video here ?
Thanks !Best regards,

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

@Guzt I had forgotten completely about this aspect ... Thank you for reminding me !!

Does offline navigation not solve this issue? Or are you even with offline navigation depending on a good/solid/working GPS connection?

Using off line navigation or not, always switch off roaming in Switserland. They have their own telecom rules and are not part of the EU which implicates that the EU roaming agreements don't apply for them. As soon as your telephone makes contact to a Swiss telephone service, costs kick in. To avoid this, use a Swiss eSIM .

For the roaming you just need to check your contract. O2 does include Switzerland in roaming from the UK

https://saily.com/download-esim-app/@Guzt However, this is only partially true. For example, Deutsche Telekom's tariffs include roaming in Switzerland and the UK.
I can't comment on other providers. -

https://saily.com/download-esim-app/@Guzt I mentioned this before... That's not entirely true! There are Dutch providers that simply consider Switzerland an EU country. For example, with my Dutch mobile plan, I'm allowed to use 50GB per month from my Dutch data bundle in an EU country (including Switzerland). So you really need to check the terms and conditions of your provider in your own country!

My provider blocks Switzerland just to avoid the possible surprise. I have to activate it or buy a data plan for it. But then, Belgian telecom is so what the most expensive in the EU.
So it is up to Adrian to check this with his telecom provider.SP2820, 550, 660, 590 Mapsource, Tyre (met de nodige conversaties tot hierboven), Kurviger, Routyou, MRA, App68studio,.. en BC natuurlijk

Time to shop elsewhere

@Nomko-Nomden offline navigation depends also on good GPS receive. Means: you don't need roaming/eSIM for Internet connection. But in long tunnels, you will loose GPS - and if there is an exit inside the tunnel, you need to take- MyRoute-App may will not navigate you!

i drove through many tunnels in Norway today, including the 25km long Laerdals tunnel. MRA worked without a glitch inside these tunnels, no spinning, no jumping to roads above the tunnel. This is with the 5.0.3 version. I even had a shaping point inside one of the tunnels and that worked as well.

@Herman-Veldhuizen ...then you are lucky.
The reasons are:- Navigation systems can also interpolate their own position from direction and speed. But that only works in straight tunnels.
- In some tunnels are so called beacons installed, by this navigation systems can also calculate the actual position (in GoogleMaps, this option must be activated in settings).
- In other tunnels there may be TunnelSat installed. This is an advanced tunnel GPS system that extends reliable satellite navigation underground, delivering accurate, real-time positioning signal.
It depends on the tunnel operator.
Nothing is impossible ;-)

@Guzzist the fact that it worked in all tunnels made me think that HERE maybe has made an improvement (i assume a newer version of the sdk is used since I last tried it). The cursor followed the tunnel shape.
I will soon drive through the tunnel again in which I know MRA was struggling.
I dont think that I made any changes on my phone to settings to improve the gps accuracy. -
Never knew about the beacons in tunnels or activation in settings. Just activated mine in Google maps. Thanks for that.
