Cant get it to work with a cable. I tried a flash drive works fine .I tried a droid razr maxx it works fine. Bluetooth work . Cant get it to work with the s5. Tried few cables nothing works. Just pickup a 2015 cx5 gt. today

 

So your saying the USB port doesn't work at all?
or that your phone doesn't connect thru the USB port?

 

The usb port works with every thing but the samsung galaxy s5 running Android 4.4.2
