    Hi Guys!
    I bought my iPhone 4s about one year ago, I never had any problem during my usage. Yesterday I connected it to my new Pioneer App Radio 2 (by the way really nice) and I noted that the iPhone display becomes yellow at the top on the left, this is happening always!

    Now I am really worry to connect my iPhone again, do you have any idea? what do you think?
    By google search I found a lot of links about yellow displays, but nothing connected to my case.

    And believe me this is really happening, every time i connect it to the cable coming from the radio..I cannot believe that the expert who assembled the Radio did a mistake..i will investigate..but please let me know if you already heard something similar!

    I am willing to be on cooincidence.
    Is it still yellow after pulling the plug?

    Basically that cable just allows you to mirror from phone screen to head unit screen. I dont even think it is possible for this to be caused by the Pioneer

    I can film the scene:
    1) iPhone display is ok
    2) I plug it to the cable
    3) sometimes the yellow tint become immediately visible
    4) I use the App Radio, everything works perfectly
    5) I unplug the very hot warm iPhone and I have the yellow tint, which will gradually disappear during the day..

    This is not happening when I connect the iPhone to another cable, just for checking if it is a common behavior..
    Is it possible that who installed the Radio selected a wrong voltage exit/standard or something similar for the cable used by the iPhone? Because it is happening just in this situation..

    I hope just to do not loose my phone during a long trip..

    thanks for your answer!

    Just taking a stab at this but it seems like the Pioneer might be pushing too much current into the iPhone. Can you use another device to test with?

    same idea, I am going to check with my iPod classic.. but really strange and I cannot believe that this is the root cause
