I have not been very pleased with my bluetooth, the people I am talking to always complain that I am cutting out and that they can't hear me. I am almost to the point that I don't use it anymore. I called Mazda Customer Service and they informed me that there was a TSB on this issue. The TSB is 09-036/10. I have talked to my dealer and plan on getting it worked on next week. Has anyone else done this?
