Try changing your update preferences several times back and forth. I didn't have to though. Picked mine up last Saturday and on the 2 hour drive home was notified there was a software update available and it was waiting for wifi.
That reminds me. There is a software update in the app (android at least) that I have checked. I don't know what it does but I have it checked. Also, I'd have to look but I think there is one in the car that is something like get it early? Or something like that that I have checked. I just checked the app and don't see it so I'm thinking it is in the car. Maybe under software?
