Thank you both for your help,here's what I finally found out after a week on the phone with HD and on the HD CVO and ZUMO forums; 1 certain bikes only have half of the 6a and 6b connector 2 with the (693000023 ) you only need half 3 The directions for both the NIM and the IPOD Connector kit have the wrong wiring sequence, If you follow the directions for the Nim it will tell you if you don't have a 35 pin connector on your bike you should follow the directions for the Ipod connector harness The problem is even if the Nim directions were revised the Ipod kit wasn't thus the 2 wires don't get switched 4 the speaker switch has to be in the down position.On another note ,yes you do need the y connector to listen to XM MP3 or Gps through the speakers and yes it has to be a HD stamped zumo.Mine works great now.My new 665 zumo is now locking up and I'm waiting for a new one from HD,If it's not one thing it's another.I did notice with all the volumes turned up the xm still has a lower volume than the radio,Any suggestions on xm antenna placement would be appreciated. Thanks again
