General Motors removed Apple CarPlay and Android Auto from its 2025 EVs, including the Chevrolet Blazer EV, citing privacy concerns while shifting to Google's Android Automotive OS. The decision sparked significant consumer backlash. An accidental A/B test emerged when Honda launched the Prologue EV, a rebadged Blazer EV built on GM's Ultium platform, but retained CarPlay and Android Auto integration.

Sales data from the last 2.5 years reveals a decisive consumer preference. In 2024, the Honda Prologue outsold the Blazer EV by 42.8% (33,017 vs. 23,115 units). The gap widened in 2025 to 73.1% (39,194 vs. 22,637) and reached 165.5% in the first half of 2026 (8,407 vs. 3,166). Combined, the models sold 129,536 units, with Honda capturing the vast majority.

The identical underpinnings — including GM key designs with Honda logos — isolate phone integration as the primary variable. Drivers are voting with their wallets for smartphone mirroring over proprietary infotainment systems. The market signal raises questions about whether GM will reverse its strategy as the Honda Prologue continues to outsell its Chevrolet Blazer EV donor vehicle by a widening margin.
