What is the default routing service?
If you do not choose any, the default routing service is Automatic - chooses Online compute if you are connected to the internet and chooses Offline compute otherwise.
In what units should I input the value for the tilt of the camera?
The tilt is calculated in degrees (from 0.0 to 90.0).
Why can't I see the map? Why isn't the routing working?
Please make sure that you either enable the online map streaming or download an offline map and load it. Without a map, the SDK can not calculate a route nor do any operations that would need it. However, the online search will still work.
