Kenwood kdc mp 232 how do I get to the aux when

put a cd cleaner in your cd player see if that helps.

Just plug the cord into the front of the cd player where it says "AUX" and then plug the other end of the cord into the headphone / line out jack on any ipod or mp3 player then select "AUX" instead of CD and the sound will come through the system

Apparently, this auxiliary input only works for a Kenwood CD changer or a sirius radio connection. At least that is my conclusion after finding the same problem. Let me know if you figured anything out on this.

You have to have the Auxillary cable plugged into the radio, and have it plugged into your device (ipod, phone, mp3 player) then hit the source button until you see Aux, then you have to start the music on your ipod or whatever your using and it will play through the car speakers

You can download the manual and specifications.

On the Kenwood models that are within about 6 or 7 years old or newer, there is an iPod adapter for the head units that plugs into the CD Changer port on the back of the radio. Kenwood makes an adapter (KCA-IP500) that gives direct control and charging through the radio and several companies make aux input adapters for Kenwood radios that will connect to the iPod's headphone jack.

you have to activ ate the aux port form the menu, on standby hold the menu button and then use the control knob on the right to change the aux to on1

it should be in aux try to press source buton and see if that is an option if not an alternative is to hook it up on the back of the cd player in the audio in or aux or aux 2 using a wire adapter from walmart in the car sterio section

There is a RCA cable that comes off the back of the radio and also another cable for 3.5mm (mini-stereo jack) that also comes off the back of the radio. The RCA jacks can be used for "AUX" or "Sub-woofer" and the 3.5mm jack is just for "AUX". Your ipod can use the audio output jack or the headphone jack and plug that into the 3.5 mm jack on the back of the radio. You will need a "3.5mm male" to "3.5mm male" stereo cord that can be purchased at Radio Shack or Best Buy. Then you select "AUX" on the display with the source button to listen to it. You may need to go into the menu and activate the "AUX" input. Check your owners manual for details.

Yes, you can. It took me almost a month and about 70 dollars wasted to lfigure it out though. All you need is the the audio jack. Its a simple chord that runs to your aux jack in the back of your head unit. MAKE SURE YOU HAVE ACTIVATED THE AUXILLARY CONTROLS ON THE CD PLAYER. YOU DO THIS FROM THE MENU SCREEN. The chord cost like five dollars at wal-mart.
