How do you hook up your ipod through the rca cable hookups in the back without the radio still playing?

This is different on every stereo, but generally the RCA ports in the back of the stereo are labeled "Aux" or something to that extent.

First, you must purchase a headphone jack to RCA cable which can connect to both your stereo and your ipod.

Connect the cable, turn your ipod on and start playing a song. Turn the volume on the stereo to a moderate volume so you can hear when the song is being played through your stereo. Then, using the selector switch, turn the stereo from "Radio" to "Aux" or whatever it says next to the the RCA plug ins on the back.

You can only do that if the rca jacks say aux. The rca's are usually for an amplifier
