I have a 2010 Prius III JBL w/o Navi. Two simple questions that I can't seem to find definitive answers to: #1 - Does the Otto Navi have 4 or 6 channel RCA output? (ie. 2 sets or 3?) #2 - Will the car's bluetooth integrate fully with the Otto Navi? Including the built in mic? (not the 3.5mm jack in the center console, but the actual mic that is used for your voice when you are on a call).
