iPhone 4s & Pioneer App Radio & yellow display!!

[mrfabio]

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!

ciao

Exactly this effect:

but it is not right: I got it after more than one year of usage..

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
