17 October 2007 - Boards have arrived!
The stock of CDCEmu circuit boards are now filled again, and assembly and testing of new units are underway. I'm currently working on assembling and sending the preorders I have received the last few weeks, and I expect to finish shortly. Meanwhile, I accept new orders - use the 'buy now' button below to order your unit!
Background
I have a CQ-DFX301N car stereo in my car, and I lacked the support for reading CD-RW discs and MP3, and it didn't have an auxillary input. What it did have was an input for a Panasonic made CD changer, so I figured I could do something with that.
I found a DIN 8C port marked CDC on the back side of my head unit. After some research, I found out that the port is a communications port for a Panasonic made CD Changer. I figured that this port must enable the (Auxiliary/AUX) RCA inputs marked CD-C-IN, and so the CDCEmu unit was constructed.
I often get the question if it's not just a question of shorting two pins. The answer is NO - never try it, it will not work! The radio must receive a valid signal to enable the CDC inputs. If it does not, the CDC input is disabled within a second.
How to order
- The CDCEmu v4 is available for sale. It is €22 plus €3 shipping (world-wide).
- Your unit is usually shipped the next business day via regular air-mail. In some cases, it may take up to a week to dispatch (restocking).
