Adding a line-in to Picasso CD? - Steve Pearce
Does anyone know of a way of adding a line input to the standard Picasso CD? I have a MP3 player I would love to play through the speakers but with a lack of cassette I have no easy way of interfacing. I was hoping to make it think I had a CD multi-changer (which I haven't) and fake it somehow.

I guess the Picasso CD is a model-specific unit, so unless it has a line-in jack, methinks you're out of luck :-|

Unlikely you can use the CD changer jack. Its umlikely to have an aux port. Your best bet is an in line rf modulator in the aerial lead.

I suspect it can be done, these people seem to be inventing adaptors to do just this:

However they don't have one for Citroen yet.
