1. A method for selectively rendering vehicular navigational instructions in a vehicle in which a vehicular two-way radio is already engaged in a dispatch voice call, the method comprising:
- transmitting or receiving audio, via a transmitter and/or receiver at the vehicular two-way radio, in a dispatch voice call and, while transmitting or receiving the audio in the dispatch voice call;
monitoring, by the vehicular two-way radio, the dispatch voice call and identifying one or more vehicular navigation instruction rendering parameters associated with the dispatch voice call;
determining, as a function of the identified one or more parameters, a level of importance of the dispatch voice call;
identifying a first vehicular navigation maneuver in a set of vehicular navigation maneuvers for providing driving directions to a driver in the vehicle; and
determining that the level of importance of the dispatch voice call meets a predetermined level of importance, and responsively rendering, over a speaker in one of the vehicular two-way radio and the vehicle, a navigational tone associated with the first vehicular navigation maneuver and not rendering a voice navigational instruction associated with the first vehicular navigation maneuver;
determining, by the vehicular two-way radio, that the dispatch voice call has ended;
identifying a second vehicular navigation maneuver in the set of vehicular navigation maneuvers for providing driving directions to the driver in the vehicle; and
subsequently rendering, by the vehicular two-way radio and as a function of the determining that the dispatch voice call has ended, a second voice navigational instruction associated with the second vehicular navigation maneuver over the speaker in one of the vehicular two-way radio and the vehicle.

Abstract
A method and apparatus provide enhanced navigational alerts for a vehicular two-way radio operating in a dispatch communication system. The integration and prioritization of navigational alerts with dispatch voice communication ensures that navigational alerts do not compromise mission critical voice communications. Navigational alerts in the form of navigational voice instructions and navigational tones are selectively prioritized based on predetermined parameters associated with the dispatch call.

10. A vehicular two-way radio for selectively rendering vehicular navigational instructions in a vehicle while already engaged in a dispatch voice call, the radio comprising a controller configured to:
-
transmit or receive audio in, a dispatch voice call and while transmitting or receiving the audio, via a transmitter and/or receiver, in the dispatch voice call; monitor the dispatch voice call and identify one or more vehicular navigation instruction rendering parameters associated with the dispatch voice call; determine, as a function of the identified one or more parameters, a level of importance of the dispatch voice call; identify a first vehicular navigation maneuver in a set of vehicular navigation maneuvers for providing driving directions to a driver in the vehicle; and determine that the level of importance of the dispatch voice call meets a predetermined level of importance, and responsively render, over a speaker in one of the vehicular two-way radio and the vehicle, a navigational tone associated with the first vehicular navigation maneuver and not render a voice navigational instruction associated with the first vehicular navigation maneuver; determine that the dispatch voice call has ended; identify a second vehicular navigation maneuver in the set of vehicular navigation maneuvers for providing driving directions to the driver in the vehicle; and subsequently render, as a function of the determination that the dispatch voice call has ended, a second voice navigational instruction associated with the second vehicular navigation maneuver over the speaker in one of the vehicular two-way radio and the vehicle. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
