I Recently got an 05' 4.4i w/ nav (non DSP) I’m trying to determine if if I have Bluetooth capabilities. I looked in the back trunk area and see the unit that has the PK number on it (don’t know what it’s called) and the antenna on top of the rack with the purple /black cable. I see on the steering wheel the (talking man) button and R/T button. But when I press the talking man button nothing happens. Is there something wrong with button, unit, or is it just a button that doesn’t do anything with out some kind of option I’m missing. The R/T button just says empty phonebook. I don’t have the cell phone adapter for the center console. But form what I’ve heard it wasn’t necessary. The talking man button is for the voice control is it not? And should hear a tone after pressing it. And is also used for pairing cell phones, or am I completely misinformed. Any help would be appreciated.
