I'm certainly no expert, but as far as my reading told me any CIC hard drive based system - which yours is - can be updated via USB in the glovebox.
If you have a 32gb drive available (or a sd card on an adapter etc) you can get as far as needing the FSC code very easily - this will at least confirm it is possible.
It would be a good idea to stream some music from the drive/card first to check it is working ok and the car will recognise it - don't forget to delete everything from the drive before putting the nav data on there.
