I want to add a bluetooth module. I looked inside the tablet but I'm not sure where to connect the bluetooth module. I think all that is needed is power, receive and transmit. There is an icon for Bluetooth but there is no hardware. Has anyone experimented with this? I need bluetooth because I want to run the Torque app with a bluetooth adapter so I can run diagnostics on my car. There are no OBD 2 apps available for Android that run using wifi. Any help would be appreciated. Thank you.
