Hi. I have my Rider 400 connected to my iPhone and my headset (From Schuberth and on the positive list). When I getting driving directions it often sound as the Rider 400 voice is hoarse. It is worst when I am nearing a turn. First the Rider will inform me of an upcoming turn. That sounds fine. But very near the turn the Rider instruction turns horse. I can understand the direction given by the Rider but the sound quality is very bad.
What can I do?
