A control unit performs a forced decoupling of a communication link between a second in-vehicle apparatus and a short range communication unit, and couples a communication link between a first in-vehicle apparatus, and the short range communication unit when the second in-vehicle apparatus has a lower profile priority order than the first in-vehicle apparatus. Additionally, the forced decoupling is performed when, at the time of the communication request by the first in-vehicle apparatus, the short range communication unit was in communication with a maximum “M” number of in-vehicle apparatuses, and the second in-vehicle apparatus had the lowest priority order of the M number of in-vehicle apparatuses. The control unit re-couples the second in-vehicle apparatus when at least one of the M number of in-vehicle apparatuses has completed its profile function ending the communication link.
