    2005 Chevy Silverado SS - Isimple Radio
    I installed FM modulator adapter in my truck for my radio to play music from my phone and to be able to charge my phone. Install was a little tough, because of trouble finding ignition keyed power. I eventually found it in the wiring harness for my speedometer cluster. I soldered wires for the ground and keyed ignition power and shrink-wrapped wires and was able to install in dash for a factory look. The item works as it should and I am happy with it would recommend.

    Jeep Wrangler SE 2000. Plugs right in, very easy to install. Love the way it keeps the stock look of the dashboard and allows me play my own music.

    Love It
    iSimple® - FM Modulator with RCA Inputs
    For past several years, I have been using a cassette adapter to play music from my iPod Nano. There was always an annoying fizzle and sound was slightly reduced. I used to have an FM transmitter, but the sound was always horrible. This happened with several different devices. This modulator fixed all of those issues. The sound quality is great. From now I hear no hiss, no static, no distortion, no muffling. Just clear, clean music.
