What is the RF Modulator/ [sorry I'm lost on sound tech]The simplest is the plain jane RF modulator. Then tune the radio to whatever unused freq the modulator can adjust to.
Same here, never had any luck around here with the RF modulators, always got interference from all the radio stations.I always found the cassette adapters better than the RF modulators.
Many aftermarket head units feature auxiliary jacks for this purpose or you can try many model specific adapters... http://www.crutchfield.com/S-2sqkbz0Tqea/m_770/iPod-MP3-Car-Adapters.html
That's how my cd changer attached in my 95. It actually sounded really clear an never had to change the station. I actually used the same station for my changer, Sirius, and iPod FM modulator. All were really clear, but like mentioned before, you have to find a good station.steve said:They have some that will plug directly into the antenna plug, but i have never used one.
