MyLink is Chevrolet’s branded infotainment interface. It is the user-facing software layer — the home screen styling, the menu animations, the Chevy logo on boot — that runs on top of the underlying HMI module hardware. Mechanically, the same HMI hardware runs IntelliLink on GMC and Buick vehicles and first-generation CUE on Cadillac vehicles.
MyLink generations correspond directly to HMI generations:
- MyLink 1.x — Earliest HMI-based Chevrolet rollout, 2012–2013.
- MyLink 2.0 — 2014–2015. No CarPlay or Android Auto.
- MyLink 2.5 — 2016–2019. Adds wired CarPlay and Android Auto.
Vehicles displaying the “MyLink” brand at startup are HMI-based and use IO4, IO5, or IO6 RPO codes. Vehicles displaying newer Chevrolet “Infotainment 3” branding are CSM-based and use IOR, IOS, IOU, IOT, or IOK RPO codes.
MyLink failures share the same root causes and symptoms as any HMI failure: “Waiting for Update Media,” black screen, boot looping, and missing CarPlay. The fix is the same — a VIN-programmed replacement HMI.
