The mobile unit can further be programmed to monitor (67) for the event in a designated location and on a designated group channel during a predetermined time window and receive (71) a targeted message during the event on the designated group channel if a current location of the mobile unit matches the designated location stored. The mobile unit can be programmed to transmit at least one group call message response in response to receiving the group call message only when the mobile unit is in the designated location.
