First post here! 2017 RDX technology pkg, AWD. The black trim ring with silver insert that fits around SYNC control knob came off. I don't know if it was bumped when I was removing package from floor of passenger side or why it came off. Along with the trim ring is what I assume is a black plastic fastener than holds ring in place and I do not know how to reattach or if the plastic piece is broken how to replace. Reluctant to remove similar piece from other side in case I could not reattach it.
Any suggestions would be appreciated.
