Just spoke with Tech support at DICE. Tech said that since I have the 3 and 6 pin plugs I do not need the DSP adapter. He suggested I take the radio out to check of the 12?-pin connector (from CD-changer) is plugged in. He said on some X5s without CD-changers these were not plugged-in at the back of the radio. How I have to get a hex-key set.

Hey Shakiss... do you have a CD-changer in your trunk?
