Have you checked whether you can be heard by the other end when you make a phone call via Bluetooth? This will tell you whether it's an issue with the connection or the output.
Also, iPhones are a pain in the arse to work with. I've had all manner of problems connecting my wife's iPhone to several different head units, both factory and aftermarket, in three different vehicles.
