How to Turn Off the Radio in a Buick Car?

[MacAshlyn]

Here are the steps to turn off the radio in a Buick car: 1. Remove the memory card and insert it into a computer using a card reader. 2. Open the memory card and navigate to the NaviOne folder (the navigation folder). 3. Enter the NaviResFile folder (the folder for modifying port and other data). 4. Locate the file starting with FM (with a .dll extension; some computers may not display the extension if not configured, but we won't delve into that here). You can choose to delete this file or change its extension to another name, such as .txt, for easy retrieval if you want it back later. 5. Reinsert the navigation memory card back into the navigation device.
