The present invention relates to a device for wirelessly transmitting GPS receiving signals for a vehicle. The present invention is provided to wirelessly transmit GPS signals, which are received by minimizing the usage of an RF cable in order to solve the attenuation of second signals caused by cable damage while weak GPS signals received through an integrated antenna are transmitted to a head unit through the RF cable, to the head unit, thereby minimizing the attenuation of the signals. The present invention reduces the cable damage within 0.5 dB by minimizing the length of the RF cable within 50 cm. There is almost nothing to disturb the present invention by using wireless USB communication inside the vehicle. The present invention is provided to fix only a wireless USB antenna inside the vehicle and omit an assembly process of connecting the RF cable to the head unit from the inside of headlining to the front of a vehicle A-pillar, thereby simplifying a process. The present invention reduces production costs; the number of components; and weight without using an expensive RF cable around 5 m.
