Pulled Sat harness out of XM receiver box on my 07 g35s sedan, Installed interface harness 999U7-VS000 to sat cable and grounded bolt from harness. Plugged in interface box 999U7-VR002 new part number now 999U7-ST000 from everythingg35. Plugged in ipod 6th gen nano to ipod connector then to box. Ipod does not charge but plays all tracks from the playlist selected when connected to ipod cable. I can't change playlist, artist or anything else. Screen displays artist and that's it. While track is playing searching icon in yellow never changes. Do I need the extra cable 999U7-VS002 to make this work correctly or could it be my ipod or some other problem? Talked personally to my Infiniti dealer with no luck. Started from here now I'm here
