Hi
I'm baffled by some of the option Shortcuts used in the windshield in realoem , I'm considering changing my windshield at the dealership , I don't have HUD or rain sensor so I'm considering upgrading it for future upgrades ..

S302A Alarm system ,, that's understandable

S521A Rain sensor ,, that's understandable

S5AGA Lane change warning ,, that's understandable, but do I need to change / install a new hardware for that ? And what's the part no. for it? I suspect some kind of a camera

S8THA Road sign detection ,, does that comes with the lane change warning ? Or that's a stand alone sys?

S5ADA Lane departure warning , how does this differ from the lane change warning above ??

S5ASA Driving Assistant ,, what does this mean ?

S610A Head-up display ,, that's understandable

S534A Automatic air conditioning ,, that's understandable , although I can't understand why does it have anything to do with a windshield 🤷🏻

L8AAA National version China ,, what's that ???

S5ACA High-beam assistant ,, that's understandable

S430A Interior/outside mirror with auto dip ,, how is that different from the below one ??

S431A Interior mirror with automatic-dip ,, how is that different from the above one ??

S420A Sun protection glazing , is that like a UV blocking glazing embedded inside the glass ??

S3APA Windscreen with grey wedge ,, that's understandable

I'll be thankful for any explanations
