An approach is provided for presenting to a user in a vehicle a visual representation of a route for finding a parking space for the vehicle, wherein the route comprises road segments having potential parking spaces for the vehicle within a threshold of a destination. The approach involves upon determining that a visual representation of the route meets a criterion for complexity, providing a visual representation of an initial extent of the route to the user in a user interface, wherein the initial extent comprises a portion of the route ahead of a current position of the user and further wherein the visual representation of the initial extent does not meet the criterion for complexity. The approach also involves providing a route extension icon rendered at the initial extent in the user interface.
