HI all, bit late to the party on this one, but I've just downloaded the full 22gb for my Nav Pro, and when the zip file was extracted, I noticed it created two folders:
MIB I
MIB II
Never seen this before, I assume as my unit is a MIB I (Sept 2013), I just put the contents of that folder on to the root of an SD card and ignore the MIB II folder, or do I copy the lot to an SD card ?
