Audio
If the VIS is connected to the truck radio (Delphi DEA 300 or DEA 355), audio will be heard from the cab
speaker system. If there is no radio in the truck then the VIS speaker will be used.
The truck radio functions can be used normally, but if the VIS is being used and the truck functions are
accessed, the VIS functions will be overridden. If the VIS function is then selected, the radio will return to
the VIS function.
The one exception is Navigation prompts. These will always be played from the truck radio.
