GM's Next Truck Interface Bets on Coexistence: PiP Projection, Big Glass, Real Buttons
General Motors will debut its next-generation truck software on the 2027 Chevrolet Silverado 1500 and 2027 GMC Sierra 1500 later this year. Phone projection stays in the stack. Apple CarPlay and Android Auto run as picture-in-picture windows rather than taking over the full display, according to details reported by The Verge.
Some versions of the updated trucks offer more than 60 inches of combined screen real estate across the instrument cluster, the central display and a passenger screen.
Tactile controls survive the expansion. GM retains physical buttons for key functions including HVAC. The touch layer adds a swipe-down notification interface for quick access to switching connected devices, settings and privacy controls.
Towing gets native integration. The updated trucks include built-in trailer-aware navigation. The vehicle identifies a connected trailer and Google Maps provides a route accommodating that trailer.
That retention differs from GM's direction in EVs. In 2023 the company said it planned to phase out Apple CarPlay and Android Auto in its electric vehicles with Google's help, as reported by Reuters. In parallel with native development, GM will perform an over-the-air infotainment update to add native Apple Music for select 2025 and 2026 Chevrolet and Cadillac vehicles, according to MotorTrend.
Looking at what this means for cockpit architecture, the truck approach favors coexistence over consolidation. Phone projection can handle familiar phone-side sessions. Native systems retain vehicle state, cluster rendering and tow configuration. Picture-in-picture becomes the arbitration layer between them, letting both remain visible without a full-screen takeover.
In this author's view, that partitioning fits shared and work-oriented use better than a single-owner model. A full takeover forces a mode switch during navigation or trailer monitoring. A bounded projection tile lowers that cost. Keeping HVAC on hardware preserves direct adjustment. Worth flagging for enterprise buyers and fleet operators is the swipe-down device and privacy surface, which treats driver identity as switchable rather than fixed.
The broader context here is where long-term value accrues. If trailer profile, routing constraints and media entitlements live natively and update over the air, the native layer controls behavior tied to the vehicle itself. Projection then covers the phone graph that drivers already carry. For practitioners tracking automotive platforms, the test will be handoff cleanliness, how permissions follow device switches, how quickly tow state propagates to routing, and whether drivers can keep primary tasks in view. That is less visible than total screen inches, but more determinative for daily use.
