I have that under my radio and I believe that that is not part of the radio itself. I believe that black module is part of the air bag system. If unplugged with the car battery connected, owners have complained of having the seatbelt warning light stay on and having to go to the dealer to have it reset.Based on the radio list I found on this forum by year, it seems the radio I tried in my 2016 was a 2018 radio. It is likely the 2018 radio is not compatible with the 2016 and only the 2017.5 is plug and play for carplay. Just a theory. I sourced a 2017.5 and will give it another go because I’m determined to get CarPlay.
When I mentioned my radio has a box on bottom with a plug , I was referring to the attached pic. Some radios don’t have this
I’m pleased to report that the 2017.5 carplay mod on my 2016 worked!! Praise to everyone on this forum for steering me in the right direction.Thanks. Just ordered it and It won’t come with the airbag module so I’ll have to use my old one
I’ll keep everyone posted after install.
