Installation time
The installation time for cars with SA 644 is approx. 2.0 hours, and approx. 2.25 hours for cars with SA 640.
The installation time will be approx. 2.5 hours for cars without SA 640 or SA 644.
This may vary depending on the condition of the car and the equipment in it.
The vehicle must be updated to the latest I-level status by flashing before installing the retrofit. Differing programming times may be necessary depending on the production age of the vehicle and on work previously performed on the vehicle.
The installation time given does not include time needed for programming/encoding.
The total costs for the programming time should be taken into account when calculating retrofitting costs (reimbursement through warranty is not permissible).
