3rd Gen Platform: GM D2 Platform | Model Years: 2018, 2019, 2020, 2021, 2022, 2023, and 2024
This page provides the complete 2018–2024 Chevrolet Equinox radio wiring diagram for the 3rd generation Equinox (GM D2 platform). Use this guide when replacing the factory head unit or troubleshooting audio in a 2018, 2019, 2020, 2021, 2022, 2023, or 2024 Chevrolet Equinox.
The 3rd generation Equinox launched for the 2018 model year on GM’s D2 platform, shared with the second-generation GMC Terrain. It was significantly smaller and lighter than its predecessor and introduced Apple CarPlay and Android Auto as standard equipment on most trims. The Bose premium audio system remained available on Premier trims and later the RS and LT trims. A mid-cycle refresh for 2022 added the RS trim and updated the front fascia. Factory amplified trims on the 3rd gen Equinox use GM’s updated amplifier architecture, which differs from the 2nd gen system and requires updated bypass harness components. Active Noise Cancellation was carried over to higher trim levels on this generation.

Frequently Asked Questions
Does the 2018–2024 Chevrolet Equinox have Apple CarPlay and Android Auto?
Yes. Apple CarPlay and Android Auto are standard on LT and above trims of the 3rd generation Equinox. The base L trim on 2018–2021 models did not include CarPlay or Android Auto, but the LT and Premier trims do. The 2022 mid-cycle refresh eliminated the L trim, making CarPlay and Android Auto effectively standard across the 2022–2024 lineup. Both features use a wired USB connection on all 3rd gen Equinox model years — wireless CarPlay was not factory-standard on this generation.
What wiring harness adapter fits a 2018–2024 Chevrolet Equinox?
The 3rd generation Equinox uses GM’s updated D2-platform radio connector. Metra 70-2003 Wire Harness Adapter covers the standard audio configuration for many 2018–2024 Equinox trims, while amplified Premier and RS trims with Bose audio require a dedicated amplifier bypass or integration harness. Axxess GMOS-04 Wire Harness Adapter or equivalent GM integration harnesses are commonly used for amplified configurations. Always confirm your trim level and audio package before purchasing harness components, as standard and Bose configurations require different solutions.
Does the 2018–2024 Chevrolet Equinox have Active Noise Cancellation?
Active Noise Cancellation (ANC) is present on Premier and some LT trims of the 3rd generation Equinox with the Bose audio system. An ANC bypass harness is required when replacing the Head Unit on ANC-equipped models to prevent noise artifacts and audio distortion. ANC bypass harnesses confirmed compatible with select 2014–2025 Chevrolet, GMC, and Cadillac vehicles with amplified ANC systems are available from Metra and other suppliers. Confirm whether your specific Equinox has the ANC system before planning a head unit swap.
Where is the factory Bose amplifier in a 2018–2024 Chevrolet Equinox?
On 3rd generation Equinox models equipped with the Bose premium audio system, the factory Amplifier is located in the rear cargo area behind the interior trim panels. This location differs from the under-seat placement used on some 1st and 2nd generation Equinox configurations. The Amplifier drives all door speakers and, where equipped, additional speaker locations in the Premier and RS trim packages. A bypass harness is required to properly install an aftermarket head unit on Bose-equipped 3rd gen Equinox models.
What size are the factory door speakers in a 2018–2024 Chevrolet Equinox?
The 3rd generation Equinox uses 6 1/2″ Speakers in all four door panels across standard and Bose-equipped trims. The 3-ohm impedance of the factory speakers on GM vehicles of this era is an important consideration when selecting aftermarket replacement speakers — most aftermarket speakers are 4-ohm, and while they will function in this application, a slight reduction in output volume may be noticed compared to the factory 3-ohm units. Some aftermarket manufacturers offer 3-ohm or 2-ohm replacement speakers specifically designed as drop-in replacements for GM factory speaker locations.
