We recommend purchasing SD cards that have good reviews and are from well-known brands, such as BlackVue (recommended for BlackVue dash cams), Samsung, SanDisk, and Lexar. While formatting your SD can help alert you to problems and keep your dash camera running at optimal performance, the type of SD card that you possess will also affect performance.
REMEMBER: Formatting your SD card will wipe the data that is currently on it. We recommend formatting the memory card of your dash camera once a month.
