Hi, I have a 2016 Diesel 1.6 CRDi Blue Drive SE Nav 5d and the Navigation needs updating. So I downloaded the Navigation Updater, put the i30 model in (I tried putting the current software version in but it said 'no results'...) The downloaded the 6gb file, popped it into the USB of the car, and a large amount of nothing happened... Tried booting it with the unit tuned off, still nothing. Am I missing something or has somehow Microsoft Windows got involved to scupper an update? Could there be a problem with my USB input socket? (although the USB stick light was flashing away... any suggestions always welcomed please?
