Back Rear Window Red Lines Defroster
 

I noticed on some X's rear widow shows red lines from defroster more.
Maybe it's just the way the sun hits it. Any comments? Thanks

those arent defrosters ..

in the manual it says that those are part of the antenna

I think when people have after market tint installed it maked the lines more noticable.

There's at least two different types. I've seen some where the vertical lines are about 4 times the thickness of mine.

What I heard from the dealer is that some have them, some don't. It depends on the functions offered, but it is definetly an antenna.
I know this because mine originally didn't have the Antenna, but they "forgot" to order the high gloss shadow line around the windows.
In order to fix it they had to order new back windows (left and right) as well.
When the dealer orders the small back rear windows they ALWAYS have antenna's in it, very visible. Connected or not, I could not get the original ones without the antenna, even when in my case they're not connected.
So I'm assuming if you have antenna's in there from factory, they're probably functional, maybe for TV function?
I'm still trying to get blank back rear windows, as I don't like the red lines, especially when they're not even connected.
