====== How can I setup my Bluetooth (BT) headset? How about A2DP or HFP? ======

The Kurviger app provides a wide variety of settings to optimise the output of turn instructions via a Bluetooth headset. We do have users with headsets from Sena, Cardo, N-Com, and many different manufacturers.

===== What headsets are supported? =====

In general the Kurviger app is able to send turn instructions via Bluetooth. We cannot make any promises about supporting a certain device or manufacturer. As a rule of thumb, if you can either listen to music or hear phone calls from your Android device on your headset, it should be compatible with the Kurviger app. If you are unsure whether your Bluetooth headset will work, you can ask in our [[https://forum.kurviger.de/|forum]] or use the free 7 day trial of Tourer+.

===== A2DP and HFP =====

Per default Android and the Kurviger App both use the Bluetooth profile A2DP. A2DP is used for high quality media streaming (like listening to music). You can switch to the HFP Bluetooth profile (some Bluetooth devices only support HFP). Go to ''Settings'' and change the voice channel to ''Calls''.
