I can hear my head rest speakers with non Atmos music so that’s not true. Only way I notice them working is by turning my head 90 degrees right or left. The treble gets pronounced in the ear facing the head rest.

I run Wilson Audio and McIntosh at home.
I have no intention on upgrading the system in my truck. It’s sufficient for a non properly sound treated environment with road noise.
Truck was sitting unlocked, lights on auto for over a week.
jumped in this morning pulled up to our premium tank, truck left running, filled it, pulled back around, turned it off jumped out. Doors unlocked lights still on auto.
Got the 4.2.3 installed notification 10 minutes later.
Crappy...
If your truck has got an OTA update, it will tell you the last one you got when you check for updates. Other than that you have to look at your SYNC version again in your truck.
