- Summary
- Some customers may experience that the MAZDA CONNECT unexpectedly announces navigation guidance when the Connectivity Master Unit (CMU) wakes up even with the ignition OFF. The navigation guidance is announced the next time the CMU wakes up if the ignition was switched OFF while navigating to a destination was in use. This concern is caused by improper CMU software. To correct the concern, the CMU software has been modified.
