What is the difference between HFP Bluetooth and A2DP Bluetooth?
HFP stands for Handsfree protocol and is a type of Bluetooth used to make voice calls. It's popular amongst car makers today, and allows users to take calls over their car's speakers without being affected by the audio input (Radio FM/AM, CD, AUX, etc.) of the device.
A2DP is another kind of Bluetooth output primarily used to stream media (such as music). Unlike HFP, only certain inputs on your car stereo, for example, can be used. With A2DP, you'll need to make sure your input is set to "Media" or "Bluetooth" (input names may vary).
How can I switch between HFP and A2DP in the MapQuest App?
Bluetooth can be a bit tricky, so the first step in trying to hear voice navigation over your car's speakers or Bluetooth device is to make sure that it supports one of these protocols.
Some cars/Bluetooth devices only support HFP; So, if you're connected via Bluetooth and not hearing any voice commands in your car, you'll need to enable HFP Bluetooth in the MapQuest App to be able to hear voice commands.
If your car/Bluetooth device only supports HFP or you prefer to use HFP:
- Make sure the Bluetooth device is paired wtih your phone
- In the MapQuest app, Tap Get Directions, enter your destination and tap Drive
- Tap Audio at the bottom right of the screen
- Toggle Play as Bluetooth Phone Call on (to green)
- You should now be able to use any audio input in your car to hear the MapQuest App
If your car/Bluetooth device supports A2DP (music):
- Make sure the Bluetooth device is paired with your phone
- Turn your Bluetooth device's input to either "Media" or "Bluetooth" (title may vary)
- Start your route in the MapQuest app
