car play not muting audio
New car. Toyota Corolla 2023. When using Siri to send texts etc it’s not muting any playing sound such as the radio or pandora etc. I can’t hear Siri speaking over music. I called Apple and they said it always mutes audio except GPS directions. My car dealer has had my car for 4 days over the past two weeks and keeps telling me it’s my phone. Any phone connected to my car does this. Dealership is convinced it’s an iPhone setting. Suggestions? Does your car mute all audio to use Siri? Help.
