Screen Fail/Rebooted - "No Signal"

[chii429]

I was driving my car last week and received a "No Signal" message on my LCD display. At this time, no functions (radio, nav, media, etc) worked and the system rebooted itself. I was not to concerned as ironically was on my way to BMW to replace the rear brake shield as as there was a new update to its design. I let my SA know and he stated he would come back with an update once his mechanic takes a look at it.

9/14-Dropped of Car to BMW
9/15 - Received a call from SA stating that codes for "No Signal" we found and provided to BMW. BMW came back and stated to replace the screen in full.
9/17 - BMW came back to my dealer and stated they are not covering the screen as they think it is a faulty phone causing this.
9/18 - The SA went back and confirmed the phone is a newer Iphone and is demanding BMW cover under warranty

I am still waiting for an update however wanted to see if anyone has experienced this issue and what your thoughts are. Hopefully the issue is resolved quickly.

This happens to me once every few months. It seems to be a relatively common issue with F3X/F8X cars, and replacing the head unit does not correct the error. I usually just turn the car off fully and wait a few minutes and the problem fixes itself.
