Navigation software, such as what I develop, doesn't require that connection. Download the map/nav data & application to the device and it'll run with or without a connection*. Also, if we fall off the face of the planet, your software still runs, you can still navigate from A to B, etc... you just can't get updates for the map/nav data. All of which would be somewhat mandatory if trying to use Google Glass for HUD displays at sea
* In our case, it's kind of mandatory as the price for "navigation as an online service" is set at 'free' by Google & Nokia. In the offline space, however, we are able to leverage our low overheads into a price point that challenges the big guns in the market
