Laggy transmission

When I plug in my iPhone and activate google maps for direction, the phone announces the directions over the car speakers and interrupts the radio whenever a driving direction is announced as it should. However I have not been able to figure out how to control the volume of the directions independently of the radio volume. This is annoying if I don't want to listen to the radio but still want to be able to hear the google map directions. Is there a war to control the volume independently?

If the phone is connected via Bluetooth but is not the audio source for the MMI (i.e. you are listening to radio), some apps on the phone use the hands free feature instead of BT audio to play their sounds. You can adjust that volume while the MMI is in hands free mode, i.e. during a phone call that is using the MMI as headset.

Try going into the google maps app and hitting the menu icon (three horizontal lines in the top left) and going to settings (gear icon in the top right). You should be able to set the volume to "louder".

You can enable the app to send the sound as if it a bluetooth phone call so that it plays even if another source is selected. Under the same settings as above, just select play bluetooth as a phone call. This also works for waze.
