For about the last eight months my Bluetooth would only connect upon the first start up in the morning and everything worked fine on the screen along with the apps. But later in the day the only thing that would work would be the volume on the radio sometimes I could not even switch channels. Now my Bluetooth is not connecting at all. I can’t get anything to pop up on the screen when pressing the apps or the phone button and sometimes the radio station seems to try to change stations by itself.
Try giving the radio a reset by disconnecting your 12v battery for about an hour or more. Leave dome lights on while its disconnected to drain all power from the system.
