iphone 3G and CDC


Recommended Posts

After a month or two of searching and reading posts and articles on how to get my iphone 3G to play (and charge) through my CDR-220 I could not find any solutions that I cared much for. It was either a cable to play and another to charge, a cable to play but won't charge my iPhone 3G, FM static machines, cable needs adapter to charge iPhone 3G, have to get rid of your CDC to play your iPhone 3G . . . . . I figured there had to be a way that I could have a single cable, that played my iPhone 3G through the CDR-220 and charged it at the same time all while letting me keep my CDC. I know what many of you are saying about the CDC (I have read your posts), why do you want it . . . . . . I can not answer that question, it came in my car, I just wanted to keep it operational. I finally figured it out and have completed the process of installing a "contraption" that lets me play my iPhone 3G through my CDR-220, charge my iPhone 3G with the same cable and keep my CDC. It even lets me have an option of video out from my iPhone 3G for when I get around to installing a video monitor. It is a little pricey for a hack job (less than $100.00) but well worth it to me. If anyone is interested I probably can put together some kind of DIY or would be happy to answer questions. Please be patient, I am not on here a lot.

Hello Helmslaw

I would definitely be interested in a DIY (with lots of pics :) ). I too have an iPhone 3G and the CDR-220. How long did it take you and was there any soldering involved?

Best thing I learned about 3G charging is that if you just connect the USB data lines to a 10K ohm / 10K ohm divider between the USB +5V and ground (putting 2.5V on the data lines), it will charge. If you have a connector suitable for hacking then this is an easy solution because you can use a 3 terminal regulator to bring 12V down to 5V.

Another alternative is to grab one of the many cigarette lighter to USB adapters out there and wire to that, but it adds about $20 to the project.

Hopefully Apple will decide to stick with the 3G style charging when they release the new iPhone in June. I'm sick of having to switch all my wiring and adapters every time a new device comes out.
