No problem, you can also use your phone via USB but will need an adaptor which roughly 30 or so. If you notice the mileage starts flashing don't panic this more than likely the system doesn't like the drive or a song or two. This is also could be battery is faulty or needs can alignment. More than likely its the USB if not done it before. Don't update the software (unless go to dealer) as can cause mileage flash intermittent (module and ECU playing funny). Mileage flashing doesn't effect the cars performance etc so nothing worry about (mine does it because bad update and dealer checked it out and said all fine don't worry about it)
