Ok I dunno if anyone here can help me out, but here goes. I have a kenwood kdc c511 cd changer in the trunk its the 10 disk made in 1998 and I have a new kenwood head unit up front that says it works with any cd changer 1998 and up, but! I have it all hooked up and when I switch over to the cd changer I can only get it to play when I get out of the car pull the magazine out and push it back in and then the music starts but I can't change the tracks or the cd from the head unit with the remote or with just the unit. Any ideas? its really frustrating since I just bought a new magazine for the changer and that cost me 47 bucks with shipping *30 for the magazine and more for 2 day shipping*
