Aux Input on Car Stereo - Iphone

I googled this quickly, but was hoping one of you guys had experience with the situation.

I have a Kenwood DPX302 cd player in the car that has an AUX input in the front that looks like a standard headphone jack. I bought the cable at Radio Shack that has the male end on both sides, but when I plug it in to the stereo and my iphone, I get nothing. The stereo doesnt recognize there is anything in the AUX jack so I cant pick that source. Any ideas as to what I'm doing wrong?

 

that's weird, it should be able to switch to AUX even without anything plugged in.

 

I followed the manual and pressed the source button... but only "standby", radio, and CD player are available.

 

have you tried it when the ipod is playing a song, might have to have that to detect.

 

try another device on it to see if it works? maybe a different cable.

 

Maybe this is the problem... maybe I need to turn the AUX option on. Now I gotta figure out how to do that.

 

throw it in the gutta and go buy another.

 

usually its a standard practice to use the manual

which states it needs to be set when in stand-by mode.

10 seconds of googling helped this discovery.

my stereo switches to auxiliary mode as soon as the male penetrates the female

 

And begins playing Marvin Gaye.

 

The manual does a horrible job of explaining how to do it. And as you can see before your post, I did google it and figured it out... so blow me.
