okay i write what i need: - I want a bluetooth for: connect OBDII Reader for car, connect gps receiver. - I want to connect huaweii 3g usb modem for online navigation information. - I want a dvb-t tuner (mpeg4) to watch tv when i waiting. The most of android tablet, phone has a Bluetooth, and the FV-1 TV box too. I think, the driver not too big problem for other (for me is big). The most of tablets has a driver and support, the common 3g modems. The Geniatech ATV2000T has a built in DVB-T tuner. So, all what i need is works, but 3-4 device, and i want to made it to one.
