The factory cell phone in my NSX hasn't worked properly since I had it installed. It is getting power. But, there is no sound coming through the speaker. I have taken it to the dealership and their mechanics don't have an answer. All they are telling me is to take it to a local phone repair shop. That is getting me nowhere either! Considering they no longer make the phones and they are $1800 installed, I definately need to get it working! If anyone has had this problem or knows how to remedy it I would appreciate some well needed advice!! Thanks.
