Still waiting on the ipod cable to arrive before I do the install but in my research, I came across a thread here on x5world where the person said the steering wheel controls were even better than factory. There were buttons that were previously non-functional that the person was now able to assign functions to them (ie the phone button but the person had no in car phone).
