My problem with google maps is that the infotainment system takes too long to switch over to the phone. An instruction like, "in half a mile, turn left," comes out as, "turn left." This happens whether I have the phone connected through USB or Bluetooth. I don't have this problem with Apple CarPlay and Apple maps.
Unfortunately, the Lyft app doesn't work with CarPlay or Apple maps. I must disconnect both USB and Bluetooth when giving Lyft rides.
