Hi, does anyone know where I can purchase an interface adaptor to connect a Sony 6 disc changer (T69) to my OEM Chrysler PT Cruiser (2004) head unit, please?

Michael, hello.
How is much current consumption of chrysler-dodge-jeep cdc emulator?

I’d like to refine the Chrysler cd-changer connector pin-out.
9th pin is PDW that means Panel lamps dimmer signal.
3rd pin is Shield.
2nd pin is Audio ground.
7th pin is Power ground.
Also, Michael, I’d like to ask you if it is better to add a key transistor in Chrysler cd-chagner emulatror shematics? It will give the possibility to connect the power not constantly, but only when there is volltage on ACC.

Maybe stretching the topic a little but I was wondering if there was any info available on the Kenwood head unit’s wired “Remote Control” interface? I’m trying to build my own custom steering wheel interface using an AVR microcontroller. I have the front-end completed & working perfectly on an ATMEGA328 but can’t figure out the protocol and/or cmds to send to the Kenwood? FWIW my hu is a DNX9960 & any info would be

Yes, any BC548 will work.
