Focus 2003 CD6000 AUX???

Basically you can't. The radio communicates with accessories such as a cd auto changer using CAN bus commands. If the radio 'sees' an auto changer then it will accept external audio input. One way would be to borrow an auto changer and a CAN bus analyser and workout how the radio identifies the auto changer. Then use a microcontroller to emulate the auto changer and add your MP3 audio into the radio. This is specialist work.

For virtually everyone this is just too hard and not worth the effort. Why not just buy an FM modulator for your MP3 player and receiver the audio via the radio?

Which type of CD 6000 you talking about? The one with the central volume control?

OOps hit enter too early here!

What I was going to go on and say is that Bob said it correct!

I've just looked into doing it myself and found that I have that 6000 CD model with the central volume control and the CDDJ button and the only way I could get and MP3 player input was to use the iTrip type model.

You can find some more details here which may help!
