How To: Make iPhone Navigation Prompts Play Over Your Car Speakers When Listening to the Radio

Make iPhone Navigation Prompts Play Over Your Car Speakers When Listening to the Radio

Maps is great for making sure you always get to your destination, until you miss that critical turn because you couldn't hear the turn-by-turn directions.

If your iPhone is connected to your vehicle's Bluetooth system and you're using it to listen to your favorite music or Spotify playlist, then it will never be a problem. The navigation voice will always interrupt the music on your vehicle's speakers to make sure you know where you're going.

But what if you want to pop in a CD or enjoy some good old-fashioned radio? If your iPhone is not the primary source of audio, it gets a little bit trickier, but still totally possible—as long as your vehicle is indeed equipped with a Bluetooth system.


  • iPhone running iOS 7.1 or higher
  • Vehicle with built-in Bluetooth capabilities (Aux-to-Bluetooth adapters won't work)

Step 1: Connect Your iPhone to Your Car's Bluetooh

While in your car, open up the Bluetooth settings on your iPhone and make sure to pair it with you vehicle's built-in Bluetooth system. You may need to make your car's Bluetooth discoverable (see your vehicle's Bluetooth documentation) in order for it to pop up on your iPhone.

If this is your first time pairing your iPhone with your car, you may need a code. Again, see your vehicle's Bluetooth documentation to find the pairing code, or try one of the generic 0000, 1234, etc. codes.

Step 2: Enable 'HFP Prompts'

To enable the feature known as HFP (Hands-Free Profile) Prompts, you will first need to map out your desired route using Apple Maps. Once set, hit the audio icon located on the bottom right corner of your map, make sure your car is the output source, then enable "Allow HFP Prompts."

That's it. Now whenever you're listening to a CD or the radio, your vehicle's audio will momentarily switch to your iPhone and provide you with spoken turn-by-turn directions. To get a better idea of how this works, make sure to check out the video embedded above.

Must I use Apple Maps or can I do the same steps with Google Maps?

Thanks. Any idea what to do when HGP Prompts is grayed out

I have a problem with navigation prompts when my iPhone is connected at the USB port in my car (which I do because satnav takes a lot of battery) and I also want to listen to the radio. How can I continue to hear prompts?

My iPhone 7 doesn't have an 'Allow HFP Prompts' button.

Similar as above I have a Kenwood headset in the car, the user manual says the unit supports HFP.

I'm using an IPhone7 ,when I follow the Gadget Hacks steps as above to output options, there is no Allow HFP prompts check button. Can someone please assist with this issue?
