Hello to all, I have a 2008 X5 that had the USB and aux, both aren't working, the lighter is working, so I don't believe it is the fuse. I changed the module to a brand new one and still not working. So my guess is the USB hub, can someone please tell me where this is located? I've tried doing much research and am unable to find a clear answer, I found one site that says it's int he trunk which I can't find and another site that says it's under the driver's seat which it where the sub is.

Next question, I just ordered the Avin head unit, does anyone know if I need the aux to work to be able to hear sound from this head unit? Or will it work without the aux?

Thank you for your help guys...
