Help with CD Changer to Disco 01 SD

[kclandrover]

My sisterrecently bought an2001 Disco SD. She has the OEM Alpine with a CD button onit,but no CD Changer. I lookedunder the passenger seat andthought Isaw the CD Changer plug. So, for herbirthday I purchased on Ebay a CD changer which has theOEM 10 pinplug just like my 2004. When I was getting ready to install it,the plug that I thought was for the CD Changer, was not....it was some 6 pin plugged into a little tiny black box. The plug had the same SHAPE like the 10 pin, but has 6 pins. So....how do Ifind a factory cable to go from the radio to the changer....or is the 01 Disco SD radio even capable of this (it does have the CD button on the radio). My 04 Disco SE looks identical to hers, but Ialready have the factory CD Changer obviously. Thanks for any help! I have searched andsearched many websites and can't find anything....doesn't look good.
