I guess that I really don't understand why there is such an issue. Everyone should be aware that the '20 and newer Indians with RC can support Carplay. That has officially been released from Indian. What has not been released is Indian's support for Android Auto. I know that a lot of riders would like to have this capability and it may come with time. But, for now it's Carplay only.
The primary function of the cable in the dashbox is for data transfer from a USB memory stick or an iPhone. It does have the ability to dual function and provide some non QC 3.0 charging through the RC unit, but it is intended for data transfer. If you choose to charge your phone with this and your phone detects that it is a data line, your non Apple phone will act accordingly. This is NOT an issue with your Indian motorcycle. If you don't want to respond to your phones prompt, and you still want to use this cable as a charging cable, then just purchase a data block cable like I linked to in the previous reply.
