My prius's bluetooth just froze

I was trying to reconnect my cell phone to the Prius this morning, after the phone would not connect to the Prius. I tried to delete my phone from the prius with the intention of re-pairing, when the car's BT unit just froze on listening...none of the buttons on the steering wheel would work. I left it alone for about 20 minutes...but it stayed frozen.

When I got to work, it was still frozen, so I turned my car off. Out of curiosity, I turned it back on to see if the unit would reset itself. Well, now it has no response whatsoever--if I hit the disconnect key, phone off key, or talk key...I get no response.

Is there a way to reboot/reset/restart the BT on the Prius or do I have to go back to the dealership?

Thanks.

 

Actually, after an entire day at work (9 hours), when I got back into the car, the BT started to work again. I guess there is a time period in which the system resets itself. Who knows?

BTW- it was pretty warm on the day in question, so I do not think that it was due to a frozen system...
