The 2021–2024 Chevrolet Suburban shares the T1 SUV platform with the Tahoe, but brings the extended wheelbase, additional third-row space, and extra cargo capacity that Suburban buyers specifically choose. The infotainment architecture is identical — CSM-based, IOS or IOT depending on trim — and White Automotive & Media Services (WAMS) offers the same full range of OEM upgrade options for the Suburban: Google Built-In (IOK) for 2021 models, 12.3″ digital cluster, and rear seat entertainment. All VIN-programmed, no dealer visit required.
Available Infotainment Upgrades
Google Built-In (IOK) Infotainment Upgrade — 2021 Only
Upgrade your 2021 Suburban to the IOK Google Embedded Infotainment system ($999.99). Adds Google Maps, Google Assistant, and Google Play Store natively to the infotainment — not through a phone app. This hardware upgrade is available for 2021 T1 SUVs only. Available at WAMS Tahoe, Suburban & Yukon Upgrades.
12.3″ Digital Cluster Upgrade
Upgrade the base instrument cluster in your 2021–2024 Suburban to the factory full-color 12.3″ LCD digital cluster (T1 SUV). OEM unit, VIN-programmed, plug-and-play. The same cluster found in Premier and High Country models.
Rear Seat Entertainment Upgrade and Screen Replacement
For 2021 Suburban owners with IOK infotainment, the factory RSE upgrade ($849.99) adds OEM rear headrest entertainment. OEM replacement rear seat screens for 2021–2024 Suburban / Tahoe / Yukon / Escalade are also available for damaged or failed displays.
About the 2021–2024 Suburban Infotainment System
The 2021 Suburban shares the T1 SUV platform with the Tahoe and uses a CSM — IOS on standard trims, IOT on premium audio trims. It is eligible for the IOK Google Built-In hardware upgrade from WAMS. The 2022–2024 Suburban comes with IOK from the factory as the standard infotainment system. All model years have access to the 12.3″ cluster upgrade. If you’re unsure what your Suburban has, send your VIN to WAMS.
