I have a 2020 and mine also started about a month ago. every time I start the truck it will jump to FM or zero channel on Sirius. It forgets my pages of channels and defaults back to 2. It prompts me to do auto updates and diagnostics. It prompts me to connect to wifi. No matter what I select or choose it will forget and prompt the next time I start the truck. VERY ANNOYING!
I did a master reset of sync, turned off auto update, connected to wifi..... been 5 days with no issues so seems to have fixed it for me for now.
**** no more than 1 hour after I posted this it started up with the prompts again.
