Hi all, I am new to this forum. I am trying to help my cousin with her newly purchased 2015 BMW X4 35i. The car is a Japanese import and a beautiful tidy grade 4.5 car. I am trying to put NZ gps maps into it and found and downloaded the correct NEXT maps from oemnavigations.com. The maps were free but I would need to purchase an FSC code to make them work, which is fine. The problem is the car wont recognise the usb with the NZ maps loaded. As I read it may be that I need to somehow change the nav head unit firmware. Does anybody know anything about this and how to go about it? The BMW genuine download site is no longer in operation. Any info appreciated. Cheers, Stephen.
