OK, fast forward to 2024... My nephew the tech person in the family looked into this & realized that I needed and Android Adapter. When I did get an adapter:
Teeran 'brand' via Amazon.ca
, the icon in 'Projection' would not change. Looking at their website in the instructions & it is supposed to be compatible with 2016+ GM pick ups. He looked online & saw that there was an update for 2016 trucks. Mine was an early 2017 built in fall of 2016. I thought maybe whatever issue the 2016s had, mine MAY have had. Also neither truck had the RPO CPO (which apparently deletes connectivity(?). I took it to the dealer & they found that the radio RPO IO5 was up to date. The tech had an Android phone too & had no luck connecting to the truck.
The next time my nephew was here, he said, lets try 'my' adapter in his truck, a 2016 GMC Sierra 1500 w/ the IO5 radio. Lo & behold my phone would connect to his truck.
He got to thinking & grabbed the adapter he uses for the gf's phone:
We plugged it into my truck. Sure enough the icon appeared in the 'Projection' spot. He had to change my music playing app, but now I can verbally reply to a text vs the 'canned' messages. One cool feature is that I can use a hunting app to see the satellite view of the surrounding area.
I let the dealer service guys know that the no Android condition wasn't a issue w/ the truck.
So the moral of the story is, not all Android adapters are created equal. If @ 1st you don't succeed, try another adapter.
