Copy ONLY the folder named “update” to the USB.

•

Never change the folder name from “update”.

•

Confirm there is only a folder named “update” on the flash drive.

CAUTION: Confirm one final time the head unit you are about to update matches the update file
selected. Attempting to install the incorrect update file will disable the head unit.
STEP 5- Update Installation:
IMPORTANT: Always record the customer’s radio station presets and navigation favorites (where
applicable) before proceeding further as they will most likely need to be reset once the update and
re-boot procedures are completed. In addition, some customizable system settings may need to be
reset as they may return to the default setting during the update.
•

With the engine idling (or GR8 connected), plug the flash drive into the USB Port.

IMPORTANT NOTE: If the head unit does not recognize the USB flash drive during the
reprogramming process, this may be due to an incompatible Controller IC in the USB flash drive or
it is otherwise incompatible with the head unit. If this occurs, delete all files from the flash drive and
re-format it to “FAT32”, instead of “NTFS” and reload the appropriate “update” folder to the USB
flash drive. If the USB flash drive is still not recognized, please discontinue the use of that drive and
instead use a USB flash drive from a different manufacturer.
