Apple CarPlay is Apple’s smartphone-projection platform that lets a compatible iPhone use the vehicle’s infotainment display, microphone, and speakers for navigation, music, calls, messages, and Siri.
CarPlay support across GM infotainment generations:
- HMI 1.1 / 2.0 (2013–2015) — No native CarPlay support. Can be retrofitted via a WAMS upgrade kit that swaps the HMI 2.0 and matching radio for HMI 2.5 hardware plus a high-speed USB hub.
- HMI 2.5 (2016–2019) — Wired CarPlay and Android Auto supported natively. No wireless support.
- CSM (2017.5+) — Wired CarPlay supported natively. Later CSM versions add wireless CarPlay on selected platforms.
- CSM with Google Built-in / IOK (newer) — Wired and wireless CarPlay supported.
WAMS offers wireless CarPlay/Android Auto upgrade kits for many CSM-based vehicles that originally shipped with wired-only CarPlay, including Cadillac CT4, CT5, XT5, XT6, Blazer, Camaro, and Corvette C7.
Aftermarket “dongle” wireless adapters are generally not recommended — WAMS has seen them cause HMI damage and infotainment instability. The OEM-grade retrofit kits use genuine GM hardware programmed to the vehicle’s VIN.
