Hi, Been reading the forum for several months since purchase of a Mustang with Pioneer AVIC Z3 installed. Wanting to mirror my Galaxy S4 to the Z3 screen. Bought this cable on Fleabay: Newest MHL Micro USB to RCA HDTV Adapter AV Cable for Samsung Galaxy S4 S3 s IV | eBay Power the cable through the usb, hook video(yellow), audio(red&white) to the video in RCA's on back of unit. Set the settings to video on, external off. Getting awesome sound but picture is colored lines static, it is getting something because when you change the screen on the phone the z3 screen changes color as well. Any suggestions? Possible that I need an HDMI back to analog(RCA) adapter? Wanting to keep all the connections hid in console & if that's the case I am running out of power ports. Awesome board, thanks for the help Joel S.
