yeah thanks for that, i have gone into menu option and fiddled with the mic settings ,still not the answer. i have a iphone 4 with the latest software installed it connects and i can hear people talk so im asuming its working correctly except for mic problem. so i decided to remove compartment in the sunnies holder where the on /off switch is there for lights , i have noticed no mic fitted ... i will try contact toyota today to see if a mic is available to purchase and try and install myself .
