charge

Hey guys, So I've had my cx-5 for a while now, and aside from the all the great things I'm still having some inconveniences with connecting my phone to the car via bluetooth and USB. Connecting via bluetooth takes down my battery waay fast, even if I'm not using my phone in any way Connecting...

After I connect my cell phone (android) to the usb, it does not appear to be charging. I also notice on the panel it has a usb radio button but it is not lit. Can someone give me information on using the usb port. The manual is very vague. Thanks Sling
