[EX Q]: Don't waste your hard earned money. It doesn't work. The thing came with a cable to connect the AUX connection only, which did not work. It had connections for digital and usb connections, so I ordered digital and usb cables. It still doesn't work. The only thing that works is an LED light.
[EX A]: negative
