5.1.3 Tunnel view
When entering a tunnel, the map is replaced with a generic tunnel image so that surface
roads and buildings cannot distract you.
The top-down overview of the tunnel helps you orientate yourself. The remaining distance
in the tunnel is also displayed.
After leaving the tunnel, the original map view returns.
This feature can be turned off in Settings (page 232).
