Installing Dice in 2004 X5 non-dsp, factory Sirius. Hooked everything up for dry run - nothing happens. Not sure how to select cd changer, as I don't have the sound system manual - I selected CD using the audioo button.

Any thoughts?

Thanks.

I may not have been clear with my question - I selected the CD source with the "Mode" button and the display read No CD. Is there something else one must do to select the CD changer source?

Thanks.
