"Add Vehicle Signature" -Entune

Has anybody figured out how to add a vehicle signature to your texts and emails from Entune? Searched but found nothing. I can send them just fine and have "add vehicle signature" checked in the message settings but nothing is appended. I'm assuming that checking this box adds some sort of message to the bottom of your texts and emails such as "Sent from my Toyota Tundra."

**I do have the box checked on mine. This is a default photo.



Thanks.
