Bluetooth not seeing anything

[Rigattoni]

The BT module is soldered and you need someone who has the equipment for soldering on main boards... electrostatic issues and a good soldering stick.
In this case it is a work for at least 10 min. to replace the BT board.

Hi ,
the Bluetooth board is soldered in that place .For your issue, my suggestion is now you can flash the following firmware.And if it still doesn't help,you can contact our customer service to change the mother board.
Firmware :https://mega.nz/#!bDABkA5T!DAwX6VRvahISXqGjA9R4tP3G41wAz7M9BKpDMD-1dm8
Please download the files to the root content of one sd card and insert it into the GPS slot .Then enter settings -system - system update.
