OK this is an odd one..
At some point last month, I had changed the name of one of my contacts, but Google assistant won't pick it up so I changed it to back to the peesons actual name. However, whenever the person texts or calls me, shows up as her actual name on my phone but when connected to Android auto shows up as the one that I had changed it to briefly.
I have deleted and re added the contact, deleted and re-paired for Android auto, not sure what else to try? It's like Android auto is so enamored with the name I had given to the contact a month ago lol!
Try changing the contact's name to RDR lol
Someone had posted something about Android Auto being replaced?
Here's a link with some more info.
