Fitment questions

Will a radio from a 2016 Mercedes-Benz GLS fit my 2020 GLS?

The first-generation GLS (X166) ran from 2016 to 2019, while the second-generation GLS (X167) launched in 2019 for the 2020 model year, so these are different generations with different infotainment architecture. A radio from a 2016 X166 is very unlikely to be a straight swap into a 2020 X167, and you should confirm compatibility with the breaker against your exact registration before buying. Never assume fitment across a generation boundary.

Does the radio from a 2016 GLS fit a 2017 or 2018 GLS?

Yes, the 2016, 2017, and 2018 GLS all sit within the first-generation X166 platform, so radios from these years are far more likely to be compatible with one another. That said, software versions and unit revisions can vary, so confirm the exact part number with the breaker against your registration to be sure. This is the safest swap to explore within the X166 range.

Does the trim level affect which radio I need — for example, does a GLS 350d use a different unit to a GLS 500 or AMG Line?

For the Mercedes-Benz GLS, trim or engine variant does not fundamentally change which radio unit is fitted — fitment is driven by the head unit type and generation rather than whether the car is a 350d, 500, or AMG Line. You may find cosmetic differences such as different fascia surrounds or trim-matched buttons, so check with the breaker whether the unit you're buying includes the correct surround for your interior. The core unit itself is the key part to match by generation and spec.

How do I know if a used GLS radio will work in my car — what should I tell the breaker?

Give the breaker your full registration number, as this allows them to identify your exact model year, generation (X166 or X167), and factory-fitted head unit spec. It also helps to note whether your car has the standard COMAND or NTG system, as these are not interchangeable. The more detail you provide upfront, the better chance you have of getting a compatible unit.

Will a radio from a pre-facelift GLS fit a post-facelift GLS?

The X166 GLS received a mid-cycle update around 2019 before the full X167 replacement, and infotainment spec can change around these updates, so crossing that boundary is not guaranteed to work. Name the exact model year of both the donor and your car when speaking to the breaker, and ask them to cross-reference part numbers before you commit. Route this one to the breaker rather than assuming compatibility.

Can I fit a radio from a Mercedes-Benz GL (X166) into my GLS (X166)?

The GL was renamed the GLS in 2016 but both share the X166 platform, so the head units fitted to late GL models and early GLS models are often the same units and may well interchange. However, software versions and option codes can differ, so confirm the part number with the breaker against your registration rather than assuming a direct swap. This is a promising avenue but needs verification before purchase.
