I realize this is an old thread but I just wanted to pick the brains of the gurus that may know about this retrofit. I did the compass auto dim clown nose upgrade on my e46 from an X5 and while reading all the horror stories in the e46fanatics forum about the BMW assist (SOS) issues. Anyone that had the SOS on their car would burn out the electro chromatic film in the mirror due to wiring. Is there any of the same issues on the X5?
