Okay. I figured it out. I was pairing the phone to the stereo (head unit) when the stereo was in the audio device mode. As a result, the stereo was pairing the iPhone as an audio device. Hence, the streaming audio worked, but the phone did not. So, I deleted the iPhone as an audio device, switched the stereo to a mode other than audio then went through the pairing procedure. By doing so, the stereo paired the iPhone as a phone and not an audio device. Now, the Bluetooth connection works as a phone and audio device.
offroadingatc...........Thanks for the suggestion to RTFM. The Owners' manual gives a far better explanation than you did. :thanks:
