Today I noticed this L shaped filament on the top inside the windshield, driver's side and nothing on the passenger's side.

The asymmetry is driving me crazy.

Do you also have it on your NX? Do you know what is it for?

 

Not on mine 2024 350Lux. It's difficult to see... I'm viewing a thin black line... Where does it begin/end. Any chance it's not factory glass.

 

All I see is the overhead pipe in your parking garage.

 

GPS antenna?

 

There's nothing like it on my US-spec NX350. From the length and positioning my guess is some kind of in-glass antenna?

 

Yeah that thin black line disappears into the headliner. Must be a gps glass antenna or some kind of heating element.

Yes, on mine too, drivers side (U.K. right). I can feel it with my fingernail, stuck on the inside. Black on the inside but perhaps coloured against the screen itself. It does not seem very strong and would be easily scraped/polished off. I suspect it may be residue from the edge of a sticky label.
Apologies for the state of the screen - just had a Sahara dust deposited.

 

I wouldn't try to scrape it off until you figure out it is.

 

AM/FM Radio Antenna?

 

Thank you mate, your picture are much better at showing it.

Exactly my initial thoughts were some kind of leftover sticky label, but I can see it running into the headliner.

Just bothers me now every time I see it now, a can't be unseen situation 🤣

 

It may have been some kind on locating marker for the automatic assembly process.

 

which country was the car made for? Can’t tell from your location.

 

OP is in Queensland Australia, and Billst is UK, so may be something for RHD models.

 

this is what I would have thought
