I have noticed that navigation stops as soon as I enter in a tunnel (I don't know if it is a bug or if it has never been implemented, so I mention it in Suggestion, which is more positive).
A good point would be to have it going on at the same speed identified in the entrance of the tunnel.
Moreover this would enable to have a correct warning for speedcam, when it is either in or just after the tunnel.
Quite like the assume maintained speed until GPS re-connected on exit form the tunnel. The question would be how easy would this be to implement? What if there is traffic and you have to stop? Some code would need to be added, probably, to aviod the app. becoming confused ie timeouts if you are stuck in the tunnel for 5 minutes and you went in at 60mph the software could be assuming that you are 5 miles further down the road. Basic example.
Like the idea though.

Yes for sure.
Nokia Maps immediately stops when entering in a Tunnel.
Other navigation softwares (Sygic Mc Guider I had the privilege to test) does not stop in Tunnels. When, entering it continues :
- either with the speed identified when entering the tunnel
- or with the known speed integrated in the map data
When I was stopped in a tunnel (traffic jam or other), it stops few meters after (I guess that tunnels lengh is not integrated in map data) a certain period without GPS signal.
So for sure, such an implementation may require some code changes, but it is a lack not to have any information in tunnel (speedcam, direction changes, ...). And I am confident that Nokia is very interested in having a TOP navigation software !
Thank you for the support mbrett.

Thank you all for your comments. I will pass these onto the team.

For phones with a accelerometer (like the N96) can't the speed/direction still be approximated when the GPS signal disappears, like when entering a tunnel?
For this kind of thing to work you may need something more sensitive.

I've only just startd using Maps 3, I have been on Maps 2 since late last year. In Brussels we have lots of tunnels, and I noticed with Maps 2 that it did often keep running even in quite long tunnels; though I haven't yet had chance to test this with Maps 3.
Perhaps I've just been lucky and the phone has held a signal quite far into the tunnel...
Perhaps the speed could be linked somehow to the phone tower signals in tunnels?
Phone tower signals are not accurate enough for Navigation and therefor for speed calculation.
