Technology answer
A retrofit dimming product changes visible states through material behavior and controls after it is applied to existing vehicle glass. The cabin can move between openness, shade, privacy, and demonstration modes, while the visible state still depends on power, controls, encapsulation, and use scenario.
A smart roof addresses glare, overhead heat, brightness, and openness from panoramic glass. Technology review should include roof size, glass curvature, control zones, wiring conditions, and delivery inspection.
A privacy side window supports rear-cabin privacy, business reception, rest, and product demonstration. It is not ordinary tint film; side-window size, movement, control position, wiring, and regulatory boundaries matter.
The same technology can have different feasibility across vehicle models. Fitment, quote, installation, delivery, and warranty boundaries still depend on the sales-system BOM/product catalog, vehicle structure, shop conditions, and delivery records.

Retrofit dimming product FAQ
These answers help customers understand technology, product differences, and fitment boundaries.
Tint film is usually fixed. A retrofit dimming product emphasizes switchable states and depends on controls, power, encapsulation, vehicle structure, and delivery conditions. It is an applied product, not replacement glass.
They both manage cabin light and privacy, but their emphasis differs. Smart roofs focus on overhead brightness, heat, and openness; privacy side windows focus on rear-cabin privacy, side-window structure, and control position.
No. Technology information explains capability only. Vehicle fitment still requires sales-system BOM/product catalog, vehicle structure, installation conditions, and delivery records.
Share the model, model year, city, roof or side-window position, and main concern so Xuntou can assess the boundary before recommending a plan.
