Please add presilence and related paremeter (in seconds) in settings for Waze audio messages.
Beggining of Waze audio message is cut (around 2-3 seconds) if phone is not connected all the time to car bluetooth system and connects only during the message. For exampe I am listening car stereo system and waze connectes to car audio system BT only in case of message. This issue can be resolved by adding presilence to waze audio message and adding parameter in settings for the length of presilence (2-3 seconds should be enough).
Currently as workaround I am using Xposed framework on rooted android phone to manage bluetooth message delay and it works perfect, but the same can be achived on any phone just by adding silence in front of waze message in app itself.
