Hopefully this guide has served to illustrate the basic processes required so that you can figure out how to hack any stereo out there. If this OEM sound system modification is not done correctly, you will end up scull penetrating humming, hissing or static noise, which will drive you crazy. I just want a CD changer emulator for late 90’s to 00’s Fords that I can pop an SD card into with six folders, each with up to 99 MP3 files.

A simple USB powered HDMI to HDMI unit that extracts digital optical and/or analogue audio from a HDMI source signal. A simple USB powered unit that converts Composite analogue RCA audio and video to HD and full HD signals via HDMI socket.
