I am trying to draw a use case diagram for navigation. However, I am not sure if it is correct since the 'call out address' base use case is being used as included use case. Any comments on the above diagram please?

This is not a use case diagram. Your bubbles contain Actions being part if some Activity carried out by a use case. A use case shows added value an actors gets from the system under considertion. Please start at square one!
I recommend reading Bittner/Spence about use case modelling. The best read you can get on that topic.
