I have seen on you tube a guy using a blue tooth to android converter to monitor the module voltages in the Prius traction battery. It is plugged in to the obd2 port and communicates with his cell phone. I would like to do the same thing but there is no mention of the device brand in the video. Does anyone know what devices can do this? The device can be seen here irddAVZaJb4 at this you-tube video. Thanks for any help. Roger
