What do I plug my aux cable into? CDR-220?

Recommended Posts


I have a 996 & CDR-220 radio. I was/am debating putting in a full kenwood nav, but for the moment, I bought a Aux cable & plan to use my phone for both music & nav.

I bought this one:


HQRP Audio cable Blaupunkt to 3.5MM fits Porsche Becker CDR-22 CR-220 CDR-220
Could someone tell me where to plug it in?

You need to enable "AUX" on your radio. This is what I found using the search function on this site:

"Turn the radio on, hold down the TP button until Becker 1 is displayed. Turn tuning knob until AUX OFF is displayed. Then arrow down and change it to AUX ON. Turn the radio off."

I have XM radio with the cable to the head unit. There are 3 connectors....power, antenna and aux going to the XM radio. The aux is smaller than 3.5mm. If I can find an adaptor to 3.5mm, will this work on my droid phone to play music. I know this will be audio only.

This works beautifully with the CDR 220.


1. Turn your AUX on

2. Plug your Blue Aux plug to the back of the CDR220

3. Buy a male to male 3.5 mm Adaptor from Radio Shack

4. Connect your Belkin Bluetooth to 12v power (I use the aux power supply in center console and wire an additional cigarette lighter jack or you can just plug it into the stock cigarette lighter)

5. Connect your Belkin Bluetooth to CDR with the Radio Shack Adaptor

6. Place your Belkin Bluetooth control button on dash (usually on the wiper potentiometer blank plug)

7. The Mic for the wireless phone is in the Belkin Bluetooth and speakers are your sound system speakers.

Plug the blue adaptor into the back of the radio.


Opposite the yellow plug in the "C" slot (pins 13-20)

@kbrandsma - how well does the microphone work when making phone calls?

It works very well. It depends on where it is placed. I think on the wiper potentiometer blank plug is a good location, especially when the top is down. If connected to an iPhone 4S or higher you just press the button (BELKIN in Photo) and SIRI answers. The mic is in a small hole at 6:00 o'clock on button (you can't see it in the photo.) It is attached via a magnetic backing. You place a paper thin sticky magnet anywhere on the dash and then attach the button to it.
