Firmware updates can improve compatibility and stability, but an incorrect or interrupted update can make an adapter unusable. Update only when necessary and follow the instructions for the exact model.

Before updating

Confirm the adapter model and hardware revision
Record the current firmware version
Use the official update file or approved update page
Read release notes and model-specific instructions

Prepare stable power

Keep the vehicle running where safe, or use a reliable USB power source specified by the supplier. Do not remove power, close the update page or restart the phone during installation.

Run the update

Connect to the adapter as instructed and upload or trigger the firmware. Wait for the completion message and allow the adapter time to restart. Some models may reboot more than once.

After updating

Forget the old Bluetooth pairing if recommended, restart the phone and pair again. Test navigation, music, calls, controls and several ignition cycles.

If the update fails

Do not repeatedly load unrelated firmware. Record any indicator-light pattern or error message and contact the supplier with the model, serial or batch information. Controlled version management is especially important for private-label products.
