Exactly! If you drive into a tunnel, the speed sensor can continue to calculate your GPS route (time of arrival, etc).

Plus, I can have an electronic speedometer displayed on the unit; dumb to me....but I do drive through tunnels in my travels.

It's not reuired to connect though in order for the GPS mode to work.
