My 2015 70D with MCU2 recently was updated to 2023.26.7. Since then the navigation audio only comes out of the front center speaker. Before this update it came out of all the speakers. I’ve seen some posts where the opposite behaviour was mentioned (it used to only come from the front center speaker but after an update it comes from all the speakers). Does anyone know what the design-intent of this feature is: should nav audio come from all the speakers or just the front center speaker?
