Note the "System Version" (e.g., Android 9.0). Updates are specific to these versions. Prepare Hardware:

Copy the update files to the root directory of your USB drive. Connect to Head Unit: Insert the USB drive into one of the unit's rear USB ports. Trigger Update: Navigate to System Info Software Update

If updates via the Play Store are stuck, try clearing the cache and data for Google Play Store Google Play Services in the app settings. Laggy Navigation: Some users resolve performance issues by installing the Head Unit Reloaded app rather than a full firmware flash. Resetting: If the unit becomes unresponsive, use the physical button (usually a small pinhole) to restart the hardware. KEY LARGO 970 - 9 SV - Blaupunkt
