hello, I have a icbm-din player on the floor of my tahoe and the dvd screen is on the roof of the car in the center of the driver and passenger seats. The video plays however, I can not hear anything out of the speakers... They said something about it having to be on a certain radio station. But I scanned through all of them and I could not find it at all... I tried playing with the wires a little bit but still no success... Could you give me any suggestions?
