From my experience, I used two different SD cards (class 10) of different brands (Sandisk and Lexar). It made no difference (both failed). I tried different formats (FAT32, exFAT and NTFS) using both Mac OS and Win 10, this made no difference (i.e. all failed). Tried WINRAR on Win 10 and RAR extractor on Mac, failed. Tried a USB, with all the above tricks, failed. Tried to access secret menu by holding Menu button on the unit, which allowed me to see folders and files, failed. Tried using either MIB1 or 2, failed. I was frustrated almost to the point of forking out $$$$ for a dealer, but sanity hadn't left me after weeks of ISO.

What worked was using 7-ZIP on window to extract the file directly onto a USB (FAT32 format). Copied 2 folders and txt file to the root folder. It worked flawlessly. Took about an hour to update.
Lot of effort and if using a MAC there's the problem straight up.

Have never had a problem Format the card in FAT 32 (ALWAYS) d/load map to HDD, extract using winRAR, copy whole folder to SD card bung it in the car and wait 40 mins and finished
