Summary

Some vehicles may experience the symptoms mentioned below, which can be fixed with the latest software update (Version 59.00.504 or later). NOTE: For 2016 CX-9 with version earlier than 59.00.441, the tachometer function will be removed from the Active Driving Display as part of Mazda's continuing efforts to improve safety and reduce driver distraction. Please explain this to the customer before updating the software. If the customer agrees, turn off the tachometer display on the AD-Display tab in MAZDA CONNECT Settings before performing the update. NOTE: If the customer has customized MAZDA CONNECT with something like a different background using unauthorized software, make sure they know the following information before updating MAZDA CONNECT to avoid any issues later on.
