08' Prius Bluetooth Issues

I've been using bluetooth for a year without a hitch (08' Prius). As of late, I can use the MFD to speedial a call, but it can't be heard over the speaker. I have to use the phone as if there was no bluetooth (hold it to my ear). Furthermore, the volume up/down on the steering wheel will not adjust, nor will the call terminate button on the steering wheel. No sound comes from the speaker and no buttons other than speedial work, yet there is a successful connection.

The bluetooth feature is pretty much not working despite having made the connection with my phone.

The dealership is useless on this one. Any help is appreciated. Thanks,
Jeff

 

Thanks.
I'm going to register my wife's phone to make sure it's not the phone that's failing (doubt that).
The dealership has told me "never seen a bluetooth fail". This tells me they don't want to/can't deal with this one.

 

I don't know why I ever doubted my Prius!!
Turns out the problem is my cellphone.

My Prius has better reliability than a simple cellphone. Man, I love that car! :rockon:
