have people been able to identify under what circumstances a software update will be pushed/notified or is it pretty much across the board? I assumed it would happen overnight when the car is connected to wifi.
I'm on 2018.12 but don't have new maps or 2018.14 yet. just got my car back from service a few days ago where they updated to 2018.12 while they had it. since then i haven't seen any software update notifications. it didn't seem like it was automatically connecting to my home wifi anymore so I did a reset of the MCU last night and it seems to have stayed connected this morning.
Maps dispursement appears random. Notably, there’s a lot of reports that sound like failed downloads(I had this happen myself, with the 5GB download actually ending up at 9GB). But, there won’t be any notification from Tesla when it’s happening. You’ll get the release notes talking about it when it’s complete, but there’s nothing saying it’s started and no phone notification about it at all.
