As said before, only the firmware in Garmin China products can recognize these two subfiles. So even if your device is an official, say Garmin US, product you won't be able to take advantage of the features provided by these two subfiles, unless you can find a way to flash your device to Chinese firmware.
It is a myth or misunderstanding that the file '006B082300.bin' can correct the shift/offset in an official Garmin China map. In reality, the map itself is never modified, let alone corrected. The coordinates of the map are not corrected neither when they are displayed on screen or recorded in SD card.
What contained in the bin file is actually a piece of code to add shift/offset to the coordinates received from the GPS chipset before they are sent to the navigation software. The same algorithm used to shift the China map is used to shift the GPS coordinates. When the navigation software displays the shifted GPS location on the shifted map, it looks as if there was no shift to the user because the amount of shift is the same. An illusion after all. However, the recorded waypoints, routes and tracks will all have shifted coordinates which cannot be exchanged with Google Earth and other regular GPS products/software.
Similar to the two subfiles above, only the firmware/software in some Garmin China and Garmin Taiwan products can recognize this bin file and activate the shift adding (not the mythical correcting) feature. That's why most non-Garmin-China/Taiwan devices have to use shift corrected maps like Venus maps.
