I don't answer calls when I'm driving any more; did that for too many years in my career (tech support). If someone really needs to talk to me, they'll leave a VM and I'll call back when I'm stopped.Do you not use the mic? My wife tells me it's terrible with out it.
For that matter, I don't even have the phone connected to the radio. There isn't anything on my phone I can't stream directly on the radio.
