Confirm OEM warranty boundaries first
OEM warranty belongs to the automaker, dealer, and the specific vehicle terms. Installation planning starts from warranty status, modification restrictions, and the vehicle systems the owner is most concerned about.
01Vehicle warranty status
02OEM or dealer terms
03Concerned vehicle-system boundary
Then confirm installation boundaries
Xuntou separates installation position, controls, power routing, shop conditions, and inspection records so product warranty, installation responsibility, and OEM vehicle warranty are not mixed together.
01Installation position and glass structure
02Controls and power routing
03Inspection and record keeping
Why the BOM scope matters
Fitment should return to the sales-system BOM/product catalog first, confirming model, product series, material scope, and installation range. Without fitment scope, installation or warranty outcomes should not be promised.
01Sales-system BOM fitment records
02Product series and material scope
03No fitment shortcut
How Xuntou reduces warranty disputes
A clearer workflow is assessment before quote, quote before installation, and documented delivery after installation. Product, installation, controls, inspection, handover, and after-sales records make later communication evidence-based.
01Assess before installation
02Record product and installation scope
03Keep delivery inspection proof
