Visit an Authorized Dealer: Currently, full system and firmware updates must be performed by an authorized MG dealer or service center. They connect your car to specialized diagnostic equipment to ensure the software is installed correctly.

Service Appointments: Most owners receive these updates during their annual service. However, if you are experiencing specific issues (like jerky lane-keep assist), you can book a dedicated appointment.

Duration: A firmware update can take anywhere from a few minutes to several hours, depending on the file size and the vehicle’s current software state.

Cost: Updates related to safety or warranty-covered fixes are typically free of charge.
