hi, i've purchased a used 2006 gs300 a while back but this is my very first post. i was wondering if anyone has had the problem i have with the bluetooth/nav; while making a call (bluetooth sync to iphone), dialing the calling, my bluetooth makes a loud buzzing noise for 3 to 4 seconds, sometimes longer before you hear the ringing. does anyone know why it does this? i asked the people at the dealer and they said because the iphone is not compatible with the lexus bluetooth system. please help me get rid of this annoying loud buzz!
