What to do if my Whistler Radio does not recognize the SD Card?
- DDylan PriceAug 6, 2025
If your Whistler Radio isn't recognizing the SD card, there are a few potential reasons. First, the SD card might not be properly formatted. Use the PC Application to reformat it, ensuring that if you use Windows, the card format is FAT or FAT32 with 32kB clusters, and all three boxes are checked. Another possibility is that the SD card isn't fully inserted. Press the SD card into the slot until you hear a click, ensuring it's completely in place. If neither of these solutions works, the SD card itself may be defective, and you should replace it with a new one.
