Where can I get a replacement ipod/iphone wire for my xcarlink???

I have an xcarlink for my 06 mazda 3 and it recently stopped working. Im guessing its the wire because I bought an aux wire and plugged it into the xcarlink and it works fine. The problem is I like using my car controls to skip tracks/playlists.

I dont know what the wire is called, I just know its an iphone plug at one end, and a circular 8 pin plug on the other end. The pins are placed 3 at the top, 3 in the middle and 2 on the bottom. Any help would be greatly appreciated.
