Hello,
I am not really that new to the world of car audio but am having a problem with the simple installation of a newley purchased FM modulator and hopefully you knowledgeable people can help me out.....
I installed the FMM100A into my father's 2000 chevy silverado so I he could play his mp3 player through the factory radio. I have checked and re-checked every possible aspect and cannot get any sound through the FM selected frequency.
The install is very basic, connect the power to the positive on the battery (or radio power), ground to a ground, plug the modulator basically inline between the in and outs of the antenna route (with adapters), plug the mp3 player y adapter into the rca inputs of the modulator and flip the switch and you should be able to hear sound on 88.7 or 89.1 as long as you match the selected frequency on the modulator to the tuned radio station. I can hear a slight difference when I flip the switch on. I can hear a slight radio station coming in (you know when you are one frequency away and the radio is trying to pull in the signal) and when I flip the switch on it cuts it to complete static and I cant hear any reception. I am assuming this is what I want to since it is a sign it is cutting the radio reception out so I can play the signal from the input device.
The only possible thing I can think of is for some reason the one adapter from standard to GM mini size is not allowing the signal but the radio stations come in when in regular radio mode so I don't think that is it. Also, they make a FMM100A and FMM100 but I think the only difference is an inline filter for noise.
What an I doing wrong?
TIA
