Isn't the "reset default" option somewhere in the setup? That deletes all user applied settings. I'm wondering if that includes radio stations. Seems almost as severe as disconnecting the battery, but not quite.
I think this reply from "Ask Toyota" might be relevant. This was my question:
"How do I delete the entune apps that I do not want?"
