I just fitted a CARK-1W handsfree car kit into my 2002 9-5. Basically I followed the excellent instructions provided at
I works very well except that there is too much delay in muting the radio and switching the phone through. If you make a call (using voice dialling or the phone keypad) then the call can be answered before you get to hear it. I wonder if this is a function of the car audio, my phone (Nokia 6310) or the CARK-1W. Anyone know?
