generating a set of maneuvering data indicating an amount of maneuvers on the route for a predetermined time period, wherein the set of maneuvering data comprises, for each maneuver of the amount:
(i) a playable media file comprising at least one maneuver instruction describing said maneuver of the amount; and
(ii) a playback cue including a timestamp for playing the playable media file on the user apparatus, wherein the timestamp is generated based on a predicted traffic-based travel time on the route from a predicted user apparatus location to a location of said maneuver of the amount;
transmitting the set of maneuvering data to the user apparatus for providing the navigation instructions.
