New icon on I-Drive screen

A new icon appeared on my screen today...

It is on the top line, near the left corner, to the right of the voice command speaker icon.
It looks like an e-mail message icon ( like the back of an unopened envelope ). My phone does not have any unread messages or voicemail.

Car is working fine. The manual is not helpful. The dealer doesn't know and is looking into it. Any ideas?

Had the same question and figured it out. It means you have missed calls. If you go to the second screen and look at missed calls, the icon goes away. Don't ask me why it looks like an envelope.

Maybe someone should write a book called, "The Secrets on the 7 Series."

Many thanks. It was driving me crazy. Now I can sleep
