Contained in the 0851 file is a ldr file and an update text file. But nothing named update.log. The contents of update.text are:
ergn,48
xrgn,12,1:/Garmin/12.bin
xrgn,14,1:/Garmin/14.bin
reboot
I'm new to all this so this may be relevant or not but when the device is connected to the pc with the SD card inside, both the device and the SD card perform like attached drives. It is as if the Garmin isn't even interacting with the files contained in the SD card.
