i bought a 2000 mercedes bens S430 and the radio was not working, it turns on but there is no sound. so i got a new amplifier, had all the wiring redone, and there is definately light coming thru the fiber optic wires, so i am very confused on what the problem could be because i still have no sound??? i went to the dealer and they told me to just get an off the market radio but when i went to my local A&S installation, he told me that he wouldnt want to charge me 2500.00$ just to have a regular radio and he would rather just fix the original fiber optic system that came with the car because it has a better sound. now i know the car phone completely doesent work and im wondering if that has anything to do with it because it might be whats in the way of the whole fiber optic signal not going thru since the phone and radio are in the same fiber optic loop....does the car phone have to work in order for the radio to work??
