Bluetooth stopped working, stays off, disconnects...

2012 Tacoma with NAV System.

Finally out to fix this issue. For the last few months, the Bluetoothconnection has worsened. I used to connect and work flawlessly. Now, the NAVsystem often won't even turn Bluetooth on. When I am lucky enough to get it on,it will turn itself off within minutes.

I know it's not the phone. I drive rental cars weekly when Itravel for business and the phone works in Fords, Chryslers, etc. And this samephone worked for the first year of ownership.

I've renamed the NAV Bluetooth and the phone numerous times.Is there a way to reset the NAV system or at least reboot? I've tried holdingthe volume button down for 20 seconds but nothing happened.

Any ideas or does it need a trip to the service dept?

 

Take it in as this seems to be very common with 2012/2013 tacomas.
