I installed the CarPlay retrofit 1 week ago with the latest cmu firmware 70.00.352B. Everything went smooth and have had zero issues using. Today however when I plugged in my iPhone the screen went black. Now no matter what I do the screen stays black and wont turn on. Even restarting the car I dont see the Mazda logo or anything. Also no sound or music. I tried the 3 button reset of back + nav + mute and that has done nothing. I also notice my iPhone is not charging or showing its plugged in. Any thoughts or anyone else have this happen. I see lots of black screen issues online, not sure if they are the same case or if their iPhone shows its charging or not when plugged in.
