This article will guide you through the procedure to make an AUX adaptor which can be connected to yours cars Kenwood CD-player which supports Kenwood CA-C1AUX adaptor connectivity to play songs from your portable media player which can be a mp3 player, mobile phone, laptop or any other device.

Check if your CD-player Head unit supports this particular adaptor or not and than move on. Few of the head units which support CA-C1AUX including mine are KDC-7011, KDC-MP5032, KDC-MP5022, KDC-MP4032, KDC-MP532, KDC-MP332, KDC-MP232, KDC-MP2032, etc.
Required Stuff
The first thing required is that you should have access to the back panel of your Kenwood Head unit
Secondly if u can get hold of a 13pin DIN connector (also used by Kenwood CD changers), that would be great, but I was unable to find one here in Islamabad so had to stick to 'desi' methods.
Thirdly you need couple of wires, a 3.5mm Stereo jack (same as standard headphones) for easy integrity with portable mp3 players or composite inputs as shown in the first picture.
Last thing you need is a 10K Ohm Resister and some tools with little technical know how.
The Making
For stereo sound, we have two channels each having a positive and negative terminal. We will be using a common negative wire and two positive left right channel wires. Connect the common negative wire to base of the Stereo jack and connect positive wires to the two small connectors on the head. (See above picture for better idea). Keep the wires as long as you wish your adaptor to be. One side of the adaptor is ready.
Now the second part; If you don't have a 13pin DIN connector ( used by Kenwood CD changer ) just like me, don't have to worry, keep reading.
Remove the Head unit from it place so that its easier to access its back panel. ( I tried to fix the adaptor without removing it but failed so don't waste your time, just remove it from the dashboard).
Connections; Place a 10K ohm resistor between pin-hole number 3 and 9 on the back panel. before moving on u can check if the player shows the mode AUX EXT or something by pressing SRC button on your Kenwood.
The resister between pin-hole 3 and 9 just tells the player that an AUX adaptor is connected.
Than connect the common negative wire from the Stereo jack to pin-hole 6 and and other two positive wires to pin-holes 8 and 12 for right and left channel. Secure the wires, I taped it to the player body.
For those who can get access to the 13pin DIN male plug don't have to do any 'desi' stuff on their players back panel. they can make a much cleaner and secure adaptor just like the one shown in the first picture by Kenwood. All you got to do is open the back side if the plug and do all the connections ( audio input and resistor ) inside the the plug. You have to take care of the numbering of the pins. When the plug is opened and viewed from inside the pin numbering will remain same as the one on deck back panel. When the plug is viewed from outside and the connecting pins are towards the viewer, the numbering is giving below.
The connections remain the same under both cases, one just has to take care of the numbering and mirror imaging.
Once done, plug that 13pin plug into the socket and play your favorite songs through the AUX input using any device.
In The Car
There is my CD player in AUX EXT mode which never appeared until I plugged in that resistor.
The 3.5mm Stereo Jack works really well, tried and tested with many players.
The jack costs 10-20RS and can be found at any hardware store. wires are cheap, usually lying around in the house, 10K Ohm resistor, hmmm I got mine from my University
