My original post has been edited to reflect that the tech installed the Navigation Interface Module on the SESG2, not XM or CB and was able to make everything work with help from MOCO.
Although the NIM is not XM or CB, the fix is instructive because it used the non-Ultra overlay harness to replace the OEM harness to which the ipod module was connected to the 35 wire connector at the HK head unit, and needed to supply power and ground to the NUOH since the normal way of doing so via the 6A/6B connector (the connector labeled "interconnect" on the NUOH) has no mating connector on the SESG2 as there is on other non-CVO fairing model bikes.
It must be embarrassing to MOCO, and frustrating to SESG2 owners, to have a CVO model loaded with features from the factory (ipod interface, amplifier, fairing lower speakers, etc.) that is non-receptive to relatively simple accessories such as XM and CB/Intercom that can be easily added to base model SG's, EG's, and RG's.
