Here are some tips to help you get the work done:
Please make sure to format the USB drive(FAT32 Format).
1. Please download the document via your computer/laptop, then use the WinZip application to unzip the file.
2. Please put the two unzipped files in the root directory of the USB drive.
(Normally, after you insert USB drive to the machine, it will detect the update pack and pop up a tip to remind you whether you want to update or not. Please click update.)
Please note that all data on this unit needs to be wiped before updating the system, so back up important data if necessary.
*If the head unit can be turned on normally, the system will be updated automatically once the USB drive is detected; Otherwise, please swipe up and down on the screen with your fingers until you see green codes appear in the upper left corner. *
