Is it the satnav Becker? If so, then just play something through the 3.5mm jack whilst selecting CD....
 
One method which was used some time ago, I can't remember the member who tried it was to record a CD of silence. While that's being played the CD system would then be active and then external audio could be fed into the ICE kit on the audio lines from the CD player. Not ideal, but it might work.
There are other methods of injecting your audio, there's a company somewhere on the net who will take your head unit and fit a 3.5 mm socket on it. Cost last time I heard was about 75 quid
Another way is to inject the audio into the VHF radio side through the aerial with a modulator. Don't use a cheap wireless transmitter, you'll be disappointed try a modulator which uses "loop-through" in the aerial lead.
There other methods which I'm sure other members will have ideas about.
 
In addition to the L+R 'audio in', I think there's a data link that the head unit uses to communicate with the CD autochanger. It uses this link to change CD's, skip tracks etc and indeed see if there are any CDs in there at all. Unless the lead you bought has some clever stuff in it to fool the head unit into thinking it's talking to the changer I'm not sure how it would work.

Brian's suggestion should work though, if you modify your existing lead to patch the 3.5mm socket into the audio L+R channels (into the head unit). However, if the audio lines from the CD autochanger have been cut I'm not sure why you'd need a CD of silence - you can fill the CD cassette with your old Perry Como and Osmonds albums, safe in the knowledge that you'll never hear them. I've not tried this by the way, and I'm not sure what will happen when it changes the CD's - at worst the head unit might mute the audio but otherwise it should just keep playing and changing.
 
My kit was a pass through, retaining (not replacing) the multichanger. I can hear the multiplayer changing discs etc, and it still plays CD’s, but when an input is provided by the 3.5mm jack, all you can hear is the Aux device.
 
Also, I did investigate the option of adding a 3.5mm jack directly to the head unit, but the company does not offer this on the Becker Traffic-pro
 
I managed to make it work by wiring the left and right and ground wires from the cd changer into a 3.5mm jack lead, i left the remaining wires connected to the cd changer. AS long as i have a cd playing in the magazine my aux input from my ipod works perfect. there is no sound from the cd and the sound quality is superb.Only downside is the changer no longer works as a changer but not a problem as all my music is now digital... Happy Days.

I don't now whether you can understand my usual hand drawn diagrams, but if you had bought the right 3.5 mm socket for your audio project you could have preserved the operation of the CD player as well as providing a point to connect your .mp3 player.
The diagram shows the arrangement for the socket which should have been used:-

I was not fussed for preserving the operation of the cd player as all my music is digital and also the single play disc in the head unit will still work, the process is reversible for when I come to part with the car if the new owner wanted the cd stacker back in action....happy days.
