Hey, I'm new. I'm no mechanical genius but can hold my own with enough reference books. But I've got a 2011 1.9 multi jet bravo. And there doesn't seem to be much help for said motor, or at least I don't know where to look!

Basically the USB port just stopped doing anything with my iPhone. Before it would happily play my songs once plugged in. Now it doesn't. Doesn't even charge the phone. I've got nothing else to try it with, but was just wondering if someone had either a handy knowledge of which fuse to check, or a wiring diagram where I can find out which one it is myself.
I'm hoping it's a simple fix and I could pull out each one to check but am hoping someone can point me to the correct one.

Thanks in advance. Please feel free to move this to whichever section it should be in if it's not in the right place ?

I now realise this should prob be in the straight 'bravo' section, and I'm not sure if I can move it. Apologies.
