If you notice, you'll see that the color of the road for the section of the tunnel is different from the color of the normal road.
And being the vector map, in fact bears with him the specifics of that stretch of road : will be recognized as all that stretch of road tunnel

Bye,bye
We bet it was before eggs or chicken?! Vector map it is coordinates inside only! No coordinates of the specifics of that stretch of road then Nuvi after losing satellites posted a question mark, stop navigation and begins a nightmare for you. It is often occurs on underground overpasses with many traffic lane even now. Garmin maps is not perfection as we know That's what I meant only...
