Does Google map navigation GPS work inside a tunnel?
What happens inside the tunnel? How do you know to exit correctly?
Thanks

I think you can still see the guide line and follow it even though your car's position doesn't update.
This: "How do you know to exit correctly?" sounds like a 5 year old wrote that. I have never driven in a tunnel that had more than one exit. Unless maybe he is talking about mine tunnels which may have many turns and many exits.

Maybe some tunnels may have a GPS receiver installed outside the tunnel which then sends the signal with wire to a receiver inside the tunnel and then uses a transmitter that re-broadcasts the GPS signals to your car GPS receivers or smartphones.
