My Mercedes has the opposite problem. It will notify me there's an OTA update and ask if I want to do it now, or not. If I just turned the car on, I probably don't want to do it now, so the question is silly. It's unclear if the "Later" option actually applies the update after I've turned the car off, or if it just means it'll nag me again later and the cycle repeats. At least it does map updates automatically.
