I just installed my iceLink into my 2005 X5 with DSP. I have a slight problem, when I turn the rear window defroster on or off, the iceLink cuts out for a half second. The DSP converter gets it power from an add-a-circuit fuse insertedinto the CD changer fuse and is grounded to a screw right above the fuse panel. I am focusing on the DSP power as I don't have a problem in my 530 which doesn't have DSP. Any thoughts anyone? thx
