I use this port to charge my phone, not to upload music as I have 6FL in the arm rest. However, recently it is only charging my phone sometimes.
It's not a biggie as I've bought a cig lighter usb socket to use instead but then I got thinking - If I get the USB fixed under warranty would they also need to update all the software on the car? Could this be a cheap way to get the latest updates? (I have £100 excess warranty).
