IntelliLink (GMC / Buick IntelliLink)

Brand Names

GMC's and Buick's branded infotainment interface, used on HMI-based vehicles from 2013 onward.

IntelliLink is the branded infotainment interface on GMC and Buick HMI-based vehicles. Like MyLink (Chevrolet) and first-generation CUE (Cadillac), IntelliLink is the user-facing software layer that runs on top of the same underlying HMI module hardware. The only meaningful differences between IntelliLink, MyLink, and CUE are the home screen styling, brand logos at boot, and a few brand-specific menu items.

IntelliLink generations match HMI generations:

  • IntelliLink 1.x — Earliest deployment, 2012–2013.
  • IntelliLink 2.0 — 2014–2015. No CarPlay or Android Auto.
  • IntelliLink 2.5 — 2016–2019. Adds wired CarPlay and Android Auto.

Vehicles displaying “IntelliLink” branding use HMI hardware with IO4, IO5, or IO6 RPO codes. Newer GMC and Buick vehicles use CSM hardware with IOS/IOU/IOT/IOK RPO codes — those don’t carry the “IntelliLink” badge.

IntelliLink shares all the same failure modes as MyLink and HMI-based CUE because they use the same underlying module. Replacement involves a VIN-programmed HMI; WAMS units ship pre-programmed and plug-and-play.

Vehicle Applicability

2012–2019 GMC Sierra, Yukon, Yukon XL, Acadia, Canyon, Terrain, and Buick LaCrosse, Regal, Enclave, Encore, Envision.

Also known as: IntelliLink, GMC IntelliLink, Buick IntelliLink
