2021 Street Glide Boom!Box GTS CarPlay & Android Auto Fix
The 2021 Harley-Davidson Street Glide left the factory with Boom!Box GTS infotainment, a system built around Bluetooth-only phone pairing rather than wired screen mirroring, so Apple CarPlay and Android Auto never actually project onto that 6.5-inch touchscreen no matter how the phone is plugged in. Riders chasing real dash navigation and music control need a wired bypass paired with a Media Box, and the 2021 Street Glide page walks through exactly which kit fits this bagger's dash and handlebar wiring.

About 2021 Harley-Davidson Street Glide Models
The GTS head unit inside the 2021 Street Glide was never designed to accept a wired CarPlay signal, which is why plugging a phone into the factory USB port only charges it instead of mirroring anything onto the dash. That single limitation is the whole story behind why this bagger's screen stays locked to Harley's native menus no matter which cable gets used.
HogPlay's Boom!Box GTS bypass intercepts that signal path directly, and once it's paired with a Media Box, the 2021 Street Glide's stock screen starts behaving like a modern infotainment system — turn-by-turn on the dash, voice dictation through the factory speakers, and no aftermarket head unit bolted anywhere near the tank.
