The mic for the UConnect is in the rear view mirror, but as you cannot hear either direction I doubt it's the mic. I would find an older non-iPhone and try it, if it works then it is more likely a Bluetooth issue. The updates may help if your car has not been updated.
The telematics module is basically the CD or CD/DVD/SR reader unit behind the bottom of the center stack.
That you can hear music over the connection suggests it likely isn't a hardware issue though. More likely a protocol issue in the blue tooth versions.
