A vehicle communication system including an interior assembly, an in-vehicle communication control located in the vehicle and remote from the interior assembly, a human-machine interface located at the interior assembly, and a global positioning system control in the vehicle. The human-machine interface is connected to the in-vehicle communication control via a connective link to communicate at least one human-machine interface signal between the human-machine interface and the in-vehicle communication control. The global positioning system control communicates at least one GPS-derived signal to the interior assembly or the in-vehicle communication control via the connective link. The HMI signal and GPS-derived signal share the connective link and are communicated via a common connective link between the in-vehicle communication control and the interior assembly.
