Iphone 6 on 2015 F30

So I recently got my iphone 6 (had iphone 5s previously) and the bluetooth seems to work fine. However, when I use usb cable and connect to it, it does not detect it. It says "Not Connected" and it is grayed out. anyone know the reason why? It does say "This accessory may not be supported" on my iphone. One reason I can think of is that the cable I am using is not a genuine apple usb cable.. I bought a 3rd party cable off amazon. This cable worked fine for iphone 5s. I guess I can do a quick test when I get home for this.



Any other possible causes???
