I called them and talked with tech support. They said no update available for mine. Then I asked when they would have the feature available and he put me on hold and checked. He came back and said no timeline. The app is supposed to auto update. It's clear in the app if you have it. It's got its own icon. Mine said not available or something like that. This was as of two weeks ago. I waited out my return window and then sent it back.
Then they really need to tell all their people this and stop advertising that it has it when it doesn't. The other units aren't going to have this feature either from what I can tell (I know my Sprint Booster doesn't).
BTW...What vehicle do have?
