Mercedes-Benz GLS Windscreen Replacement Parts

These are two different generations — the first-generation GLS (X166) ran from 2016 to 2019, while the second-generation GLS (X167) started from 2020, so the windscreens are not the same shape and will not interchange across that boundary. You need to source a screen specifically from the X167 generation for a 2020 car. Always confirm the exact part against your registration with the breaker before buying.

Yes, generation matters significantly — the X166 (2016–2019) and X167 (2020 onwards) are distinct platforms with different windscreen profiles. Even within a generation, you also need to check whether the donor screen has the correct brackets or cutouts for any ADAS camera or heating elements, as these vary between cars of the same era. Confirm all of this against your registration with the breaker.

Trim level does not affect windscreen fitment on the GLS — an AMG Line, standard GLS, or any other trim variant within the same generation uses the same glass profile. What does matter is whether the screen has the correct provision for a heated windscreen or ADAS camera bracket if your car is fitted with those features, regardless of trim. A screen from any trim of the same generation should physically fit, though confirm heated or camera-bracket requirements with the breaker against your registration.

Not necessarily — windscreens fitted with an ADAS camera bracket are a specific variant, and fitting a screen without the correct bracket or with a differently positioned one can interfere with your camera's calibration or mounting. The X167 generation in particular saw wider fitment of these systems, but whether a specific used screen is compatible with your exact ADAS setup is something you must confirm with the breaker against your registration number. Never assume camera bracket compatibility without checking.

Yes, this is an important check — a heated windscreen has embedded heating elements that connect to your car's electrical system, and fitting an unheated screen to a car wired for heating means losing that function. Conversely, fitting a heated screen to an unheated car is unnecessary and the connector will simply not be used, but it is still worth avoiding a mismatch. Check your existing screen and confirm the heated or unheated specification with the breaker before agreeing a purchase.

The GLS name was introduced at the 2016 facelift of the X166 platform, replacing the GL badge, and the underlying screen profile is the same for that generation — so a screen from a late GL X166 may well interchange with an early GLS X166. However, you still need to verify that the ADAS camera bracket provision and any heated-glass specification match your car, and you must confirm this directly with the breaker against your registration rather than assuming compatibility.
