To dig up an old thread... I've decided to get "with it" and want to play some songs from the hit parade. I'm getting an MP3 player for christmas.
I've got the OEM changer connected. I know I could leave the changer connected and break into the L, R and GND wires, but then it would always be spinning and displaying duff track info, plus I don't want to mess with the original wiring.
My plan is to buy a blue plug with 3.5mm plug connected on ebay and plug this in, but I've read in lots of places that this won't work with OEM units, as it needs to detect a changer to allow the input to work.
This is a Japanese web page that says to connect Data In directly to Data Out - apparently this will make it think something's connected.

In a discussion on alfa forum about this tactic some said it worked, one said it didn't. It's possible it was just a duff connection, as people were just using a length of cable stuffed in, as there are no terminals in these positions on the standard ebay cable.
On the other hand, if I broke into the changer's cable then I could use a panel-mounting socket that has make/break contacts. Then the changer would work as normal if the MP3 player wasn't connected. Actually that sounds like a pretty good idea. Hmmm.
Has anyone successfully connected an MP3 player to the CD changer connector on a Croma?
