Long story short. I have the USB ext. Cable in Port 2,the hdmi plugged. The input/output set to device other USB. When I connect my galaxy note 3 SM-N900 the phone device detects the hdmi connection through the official MHL 1.0 Samsung adapter but the HU doesn't identify it. When I try to connect directly to USB to micro USB the phone chargers and says connected as multimedia device MTP mode but the HU continually flashes on screen "format read". During this process the phone has a pop up message stating Samsung kies need to be installed to enable file transfer and access. I tried stock roms,
