Mine did not have a CD changer in it. I doubt that the cable in back of the radio is unplugged on mine - BSW sold me an XM radio kit with a blitzsafe as well as the Dice module. The XM radio works great - I get great sound with it and the XM works with the radio and steering wheel controls. I have a feeling that there may be a bad cable between the blitsafe and the Dice? My DSP unit does not have the coax cable coming out of it, but I do see a coax "female" connector on the upper surface of the DSP unit. So, does this mean that I also need a DSP adapter?
