Smart roof FAQ
What else would you like to know?
A retrofit dimming product fitted inside the original automotive glass, not replacement dimming glass.
How does a smart roof differ from a sunshade?
A sunshade physically blocks light. A smart roof adds an electrically controlled dimming layer inside the original roof glass, switching between open and shaded states. View the in-cabin demonstration to decide whether it suits your everyday use.
Will installation replace the original roof glass?
No. The product is fitted to the inside of the original glass. Glass structure, roof dimensions, installation position, and wiring conditions are checked before installation.
Which controls can my vehicle use?
Current product information shows button, voice, linked, and scene-triggered controls. Not every vehicle supports every function. The combination, roof zones, and operation depend on the vehicle configuration and confirmed installation plan.
How are cost, installation time, and warranty confirmed?
Share the model, model year, trim, and city to confirm the product and installation plan, then discuss cost, scheduling, and warranty terms. Check appearance, controls, and switching at handover and keep the installation records.
