I don't use an Android phone so I don't know if the navigation voice prompts will be heard through the car speakers over the Bluetooth connection. However, I do know that that voice prompts can be heard over the car speakers when using the AUX audio connection. I have my iPhone connected to the factory Bluetooth but the navigation voice prompts in CarPlay are not heard...the CarPlay music audio is just fine over Bluetooth.Thanks Ray. I think I'll pretty much only ever use the Android Auto and use Google Maps in Android Auto. I'll also pair my Android phone to the original Bluetooth, as you have advised. From what I understand, that will mean that the navigation voice prompts will come through the car speakers?
In that case, will I need to install the new microphone? I assume this is just used if you want to use the Android headunit Bluetooth?
No you don't need to install the included microphone but I always recommend installing it anyway because you might actually want to use some of the Android functions at some point.
