This is a guide to building your own cable for din to 3.5mm iPod jack.

Tools:
1) Soldering Iron
2) Multimeter (optional but good to have)
Parts:
1) a switched 3.5mm jack- (jaycar CAT. NO. PS0133)

2) a male-male 3.5mm lead

3) 6 Pin DIN Line Plug ( jaycar CAT. NO. PP0308)

4) some wire and solder
5) Two 4.7K Ohm resistors
6) heatshrink tubing or electrical tape
Steps:

1) Cut the male-male 3.5mm headphone lead and determine which wire connects to the tip of the 3.5mm plug. In the diagram bellow it is shown as red (however the actual wire may be a different colour)
2) splice in one of the 4.7K Ohm resistors, insulate the splice with heatshrink tubing or electrical tape. Make sure you reconnect the ground shielding wires also.
3) Next solder the ground wire shown in brown to the ground pin on the 3.5mm switched jack and to the ground pin of the DIN line plug. Shown in brown.
4) Solder the other 4.7K ohm resistor between the left and right change jacks on the 3.5mm switched jack. And solder the wire shown in Blue which is the input to the pin on the DIN line plug.
5) Solder the wire shown in Pink to the switch point on the 3.5mm switched jack and to the Din line plug.

6) check nothing is shorting and everything has been properly insulated, assemble the line plug and mount the 3.5mm switched jack in a location of your choosing. I place mine behind the front trunk release leaver. ( I also mounted a cigarette light above it to use for charging the iPod)

How it works:
With the 3.5mm plug inserted, both left and right channels are merged with a 4.7K Ohm resistance placed on each channel, the Blue and Pink wires are open circuited, this puts the radio into accept auxiliary input mode and the tuner is switched off and the input signal from the 3.5mm jack is played. When the 3.5mm plug is removed from the switched jack it causes the Blue and Pink wires to short, this is the same function and placing the shorting plug into the back of the radio. This effectively puts the radio back in tuner mode and you can pick up radio stations.

Important Notes:

Do not use your hacked male-male 3.5mm lead with any other system.

Check all your connections with the multimeter to insure no unwanted short circuits exist

For added safety I generally switch the radio off before pulling the 3.5mm lead, then just switch it back on to start listening to the radio.

It works brilliantly on my Blaupunkt Lubeck MY 72.
Now I only have to pick the right music to complement the sound of my 2.4E.
THANKS!

Hi. I have read your write up and instruction for making a cable for ipod to DIM for Blaupunkt radios. Thanks for doing this. I need to make one for myself. After reviewing your design, I had one question or concern. Since one resistor is inside the leader cable (to the ipod), what would happen if someone used a cable without the resistor? Say like my wife that uses a standard cable to aux in her car. I feel that there is some risk. So, I thought of a way that this could be avioded. Could you look at my idea and give me feedback? Do you see an problems with it? (PS..not sure how to add pics)

Would no matter what Aux cable you use. The resistors are in the DIN connector which is always installed on the radio.

Here is one I just built for my Becker radio. It is switchable between radio and iPod. It provides line level inputs and charge for the iPod.

Here is the info on DIN pinouts.

The iPod cable came form an eBay seller.

Will this cable also work with a Grundig Weltklang 4600VD mono radio with a 6 pin DIN connector?

The Mono version at the top of the post will work as long at the 6 pin is an input.

This is very illuminating. Thanks! I think the pinout of the DIN connector will vary from radio to radio. I can see how to do this on my Frankfurt US model, but the pinout is definitely different. On mine, there is a wire jumper behind the socket that will need to be cut. There is no shorting plug, so I will have to make one.

I see the reason the resistor is inserted into the cable. That's so the switched pins can reconnect the internal receiver to the PA. In fact, if you used a smaller resistor, you could put one of them in the blue wire between the switched jack and the DIN. The other resistor will connect to that one in a Y-configuration. When you pull the 3.5mm plug out, there will be a resistor between the pins that are supposed to be shorted. With a resistor around 100 Ohms, they will act just like they are shorted. You won't lose any radio signal. That means that the two resistors will sum at the input of the DIN when the 3.5mm plug is inserted. That way, you can use a standard 3.5mm cable with no mods.
