Put in a new head unit a year ago. Kewood model that came with BT. I figured I'd give it a try. Windows up you can have a conversation but people say "what is the noise in the background???" Windows down is hopeless. I did find it has an annoying default "feature" where it auto-answers.
I agree with the sentiment that 911 time is my time. I decided to leave the mic installed just in the off chance that I might need to answer the phone if someone REALLY needs me.
Hey, does this happen to anyone else? Wife tells me I should never answer the phone while driving (even with hands free) but then doesn't understand why I won't won't answer her repeated calls when I'm driving? It's like some kind of sick test!
