Software Update Procedure
WARNING: This page is about a different car, the 2016 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.
Prior to performing the software update, complete the preparation steps following:
- Acquire an empty branded SD Card (Class 10, FAT32 formatted). XC and/or UHS cards are not recommended.
- Load the needed update (which consists of a xxx.brm, xxx.mnf, and xxx.smd files) into the root directory, not in a folder, of the SD Card.
NOTE:
Any existing files on the card will be deleted when the new files are loaded from TIS
