Mp3 ipod adapter cable mz360136ex
 

As some of you know, the back AUX-in input has a static buzzing noise if plugged in and the phone is charging at the same time. More about this HERE.
By accident I came accross this . Apparently this one connects at the back of the stereo directly into the wiring harness. Has anyone installed one of these and can provide some feedback? Is the hissing buzzing noise gone?
