Hi,

I have been unsuccessful in getting good sound quality out of an FM modulator in my C240. I even installed a line driver (Phoenix Gold PLD1) between my music source (MP3 player) and the JVC Modulator. This improved quality and volume but is still not acceptable. I believe that the C240 head unit is designed to work with boosted FM signals, and that the FM Modulator is just not capable of providing output at that level without unacceptable distortion. What I want to do is to install the FM modulator between the rear windshield antenna and the antenna booster, so that the FM modulator's output is boosted as well. I would appreciate any pointers on where to locate the booster and on how to intercept the connection between the antenna and the booster. Thanks.
