Missing buttons with AVH-X8500BHS and iPhone 5

[oropeza]

Hi guys,

I installed my new AVH-X8500BHS and connected my iPhone 5 using all required cables and adaptors.

I go to AppRadio Mode, and CarMediaPlayer and select any option (Artist, Album, etc).

 

In there I notice that the "Back" button is missing from the top left corner.

Actually, if I press that corner I go to the previous screen, just the icon is not there.

 

The problem is worse when watching a Video, because, I can't find anyway to see the buttons (Play/Pause, Now Playing, Back) and scroll line. Once again, they are there, because I press the bottom left corner and the movie is paused.

 

Any idea what might  be happening.

 

Thanks for your help.
