    I received an up grade from china. Followed directions all screens came up as directions said. But now there is no sound and when I try to bring up my navigation it goes straight to Bluetooth. Is there a way to go back to factory standards?

    Get a flash tool and 4.4.2 or 4.4.4 ROM image from the manufacturer. Back everything up (see Backing up an Android Device). Flash the older ROM. Restore everything.
