Hello,

I don't think these are protected by a fuse. The jack has almost no voltage at all, the standard USB is only 5V. And I'm not sure if those power pins are connected in the car.

Perhaps this function can be disabled / enabled in the radio menu? Or MES?

The USB is intended to use with USB sticks I suppose, so it should have the 5V pins connected.

If you have a multimeter, you can carefully see if there's voltage on the external 2 pins inside the USB socket:

That could give us a hint.

A wiring diagram and description coming from the FIAT online eLearn. It's the only one that mentions the AUX / USB as far as I could see. Should be helpful.
