The car cannot self activate, which is a misconception many Toyota dealers (including mine) have.I've been waiting like two weeks+ for my activation. I could tell my dealer had a similar issue where no one instructed them on how to initially set up the car before allowing me to drive off the lot with it. They've claimed too, like other dealers in this thread, that it'll set up on its own remotely. Based on the 2020 data and older forum posts, it sounds like map data could be GB upon GB of data, like possibly > 50GB. If the car has to download all of this in the background, losing connection or living in an area with poor connectivity could affect the speed, if I had to guess, coming from a software developer's perspective. I know for a fact I have extremely poor 4G service where I park my cars, so I wouldn't be surprised to see this activate months from now or from driving and parking at my place of work where I'll have a better roaming data connection.
