When calling on my car phone people can not hear me. The phone has been worked on 4 times and not resolved. As long as I am driving under 30 miles an hour the phone is ok at best. I have called the service department of the dealership on several occasion and they cannot hear me, I have to pull over and tell them what I think. I use my phone for business and if I know it worked like this I would not have purchased the vehicle. It is really bad at best.
