Not sure if this helps. I had a Sony Carplay head unit installed in a 2017 Nissan Versa S Plus at Best Buy. They tried installing the same steering wheel interface and could only get volume to work. They ended up installing a Maestro - Universal Analog Steering Wheel Interface and got almost everything to work. Volume, Source, Radio/Track Seek. Phone answer works as long as Carplay is active. Not perfect, but better than before.
