What are you looking at to know that's happening? Is the Toyota downloading/displaying some information only available on your phone, or from the Internet, or something else? Could it have a 4G connection of its own? What's the connection that makes you think the phone connection is letting it upload data over the Internet using your phone?

The car states that it connected to my phone and gets internet through it. There is a specific indicator for it. I have no clue what it downloads/uploads because I use it solely as a very expensive Bluetooth speaker.
