Right Cable? It's in the settings I'm sure, just update the unit and it worked for me my build was November last year, was a my20 the salesman said.I just picked up a new 2020 XSE hatchback last night and love everything about it except for the lack of Andoid Auto; really praying they drop a firmware update for it.
The interesting thing is, when I plug my LG G7 into the dash USB port, AA actually starts and the AA button appears and Google Maps pops up on the car's screen and runs for about 20 seconds before disconnecting.
It seems obvious that AA is already present on the head unit; just needs to be toggled on in the firmware. Question is, when/if they are ever going to do this for us?
