Finally got the long awaited connector! just tested with nokia E61i while my wife driving ourselves to foot massage shop. when there is incoming call, your phone will ring. press the answer button on the phone or the remote button FIRST before pressing the 'call' icon (below headphone icon) on your steering wheel. the music will be muted upon pressing the 'call' icon and voice (through speaker near driver panel) and mic (above you) is activated.
control the speaker vol by the 'mobile phone' icon as if were audio vol. this is rather manual style and not automatic like BT in luxury cars. i suspect the nokia remote mic function still working thus may act like double mic for better voice quality for the caller.
lastly, i still cant figure out what is the headphone plug is for. i might suspect is for private listening rather then to 'broadcast' to everyone in the car. you know what i mean... dont you?? sometimes you might not want others to know your 'secrets'
so i conclude end of testing for hand-free feature for vietnamese/korean i30.
