    Periodically my 2014 Prius Two Bluetooth system decides arbitrarily that I am having a conversation on my iPhone when I am not, and the display switches to my phone number and indicates a phone call in progress. The "hang up" button on the steering wheel has no effect. I must fish my iPhone out of my pocket and manually disconnect the (nonexistent) call. Sometimes I have to do this twice to make this phantom conversation stop.

    I just posted another thread about my Prius Two and Bluetooth, but thought the two issues should be kept separate. If this is a problem with the Bluetooth system on the Prius, I would like to know that I should return the car to the dealer before my Prius Certified warranty is over.

    Remove your phone from your pocket whenever you get into your car. Report back if it happens when not on your person. Likely moving around has activated a button causing the problem.

    Or maybe you turned on "Hey Siri" and the phone thinks you're talking to it.

    This never happens to me and I've used iPhone with Prius since 2012

    It does this if you have an app (like Maps or Google Maps), set to send voice prompts over Bluetooth phone audio (or "allow HFP" in Apple Maps. You'll suddenly see a call on the display that says "My number" followed by your phone number. It should switch back in a few seconds after the app finishes talking. Apparently in order to let the voice prompts come through even when you're listening to radio or some other non-Bluetooth source, they treat it as a phone call, so that it overrides the other audio. So - you might want to check whether some app on your phone is trying to "talk." Perhaps its volume is down so you aren't hearing it? I've also noticed the Bluetooth override doesn't always work when the iPhone is plugged into the USB -- but I can't recall whether I see it make the "My number" call or not in those cases.

    If you don't have any apps running that could be sending voice prompts, and you're still seeing the "My number" calls, it might indeed be something the dealer should check out.

    BTW, I'm a newbie with the "My number" calls myself. I just switched to iPhone a couple weeks ago -- I had a different way of dealing with voice prompts under Android.
