also, in the mmi settings, you have the choice to select PAL or NTSC and to change aspect ratio to either 4:3 or 16:9. i found only certain combinations worked for my iPhone 5s at the time, otherwise it did not display correctly on the mmi screen. what settings did you choose?
Thanks for the info Audibmi, I am trying to gather everyone's input to help with my instructions. You are correct, I forgot that I made sure to match the PAL vs NTSC switch on my converter to match the PAL/NTSC option in the MMI menu. Let me add that to my list of instructions.
I was not able to get this system to work without powering the RCA-to-HDMI converter, but let me verify that again to make sure. Thanks for the feedback, keep the comments coming!
