CD Changer installed, now What? Please Help Iv'e got a 2001 Deville DTS. Installed Changer in the glovebox, found the 10 pin wire, modified the glovebox, no problem! The Changer is getting power as it is cycling through the disks, BUT the system does NOT recognize the changer as a Source!!?? Perhaps a configuration step? Any suggestions appreciated! Thanks and Happy Cadillac'n!!
