A method of managing communications for an in-vehicle telematics system includes substantially simultaneously receiving requests for communicating first and second audio signals via a vehicle audio system. The signals respectively correspond to interactive voice services (provided via a menu dialogue) from a first in-vehicle system and to a first audio messaging from a second in-vehicle system. An arbitration control selects one of the signals as a priority output and the other as a subordinate output. The priority output is provided over the audio system. A queue manager maintains the subordinate output in a queue for outputting over the audio system after priority output completion. If the first signal is the subordinate output, then the queue manager maintains a state of the menu dialogue, as of a time the priority output is selected, for continuation of the menu dialogue from the maintained state after priority output completion.
