Some customers may complain that the tachometer display in the Active Driving Display cannot be turned off using the MAZDA CONNECT setting menu since it has been removed by a CMU update. The concerns will be noticed after a CMU update from versions 58 to version 59. This is caused by the seat position memory control module storing the active driving display indication position, brightness level, and display information at the same time when the seat position is programmed. If the setting for the tachometer display was left ?ON? for the programmed position before the CMU update, the position memory control module still remembers the status and therefore the tachometer display remains.
