Please note the the way the VIDEO4 is licenced has changed. When updating the VIDEO4 both the UPDATE.RT6 and the licence.bin file should be copied over to the memory card.

Note that if you have been supplied with an updated licence.bin file from Race Technology, then you should use this file and not the one included in this zip file.

Also, please note that this file contains 2 version of the firmware, which are almost identical except for the settings for the real time video output. Most units should use the UPDATE.RT6 in "Hardware b", however if you find that the video output is either B&W or not working then please use the file in the directory "Hardware a".

Please note that in all other ways the 2 firmware versions are the same and will not affect the recorded image or any other functions - only the real time video output.
