Took the bull by the horns and stripped down centre console etc to change some wires round on my Pioneer 960BT HU i just can't get the MHL thingy to work the Mirror link wont work--ive been in all the smartphone set up menus and still no joy which basically means connectivety to my S5 is totally a waste of time i was supposed to be able to play You Tube on my screen with this--- not happening!!
