right click on the file first then.......
Most DAT files contain text, so you can open them with text editors, like Notepad, Notepad++, VS Code, and so on.

But it doesn’t happen directly, so you need to right-click on the file and hover on the “Open with” option:

I just ran across my map update thumb drive. There are two files that you will need to update your VIN in. Both are the same file name. First is in Cryptnav/Program/SDX_MY16.dat the second is in Cryptnav/Data/Data/Misc/SDX_MY16.dat. There is one line in each file that requires your VIN. It should pop out at you, but if you have trouble, let me know.

I don't know that simply changing that will work, but it's a start. I don't have access to another GM vehicle, so I can't verify whether or not it works.

As others have asked, please let us know if it does work.
