Bluetooth microphone makes it difficult for others to hear what I am saying.

Bluetooth microphone makes it difficult for others to hear what I am saying. "Repair" is to move microphone, and was unsure if I want to do this or not. Did it, and it helped. When playing Sirius radio, there is an annoying high frequency hum. The hum changes (often goes away) when accelerating. Speculation is that the issue is related to a grounding issue with some wires. There is an annoying squeak from the steering column. There is a TSB to address, but dealer opted to fix another way. There was an annoying hum from the Sirius radio. The area engineering rep had to come in to diagnose and solve the issue. They ended up replacing the entire wiring harness.
