Just wondering if I'm the only one who has callers compain about the quality of a call through the AppRadio II. I've been getting very cranky when on the phone because I really have to raise my voice to be heard, and I can't turn up the volume to hear my caller because they'll hear an echo. I have the mic about 14 inches from my mouth, hanging from the headliner next to the rearview mirror and on the swivel clip pointed right at me. I pulled the radio to confirm the mic was plugged in and everything seems connected properly. Is this just another example of Pioneer needing to improve their product?
