| Factory code | FLHX |

| Engine | Milwaukee-Eight 114 · 1,868cc / 114ci |

| Factory USB location | USB-A · inner fairing |
| Fairing Style | batwing (fork-mounted) |
The 2021 Street Glide is the year the FLHX gets the bigger engine: Harley swaps the Milwaukee-Eight 107 for the 114, while the fork-mounted batwing fairing and the Boom! Box GTS radio carry over unchanged. Offered this year in River Rock Gray and Billiard Red, its 6.5-inch touchscreen already runs Apple CarPlay — just not wirelessly until a Bluetooth headset is paired. HogPlay's Boom! Box GTS bypass removes that requirement, and a Media Box or Piglet then adds wireless CarPlay, Android Auto and streaming apps through the batwing speakers, with the USB-A port in the inner fairing and the bypass tucked under the seat.
Headset Bypass Required
The factory Boom! Box GTS radio locks CarPlay behind a paired headset. A HogPlay headset bypass removes that so CarPlay and the USB port work without one — then a Media Box or Piglet adds wireless CarPlay, Android Auto and streaming apps.

2021 marks the engine bump for the Street Glide (FLHX): the Milwaukee-Eight 114 (1,868cc) replaces the 107 under the same fork-mounted batwing fairing, with the Boom! Box GTS radio and its 6.5-inch touchscreen carried over. New shades this year include River Rock Gray and Billiard Red, and the USB-A charge port keeps its home in the inner fairing.
The bigger engine doesn't change the CarPlay story: Boom! Box GTS still gates Apple CarPlay behind a paired headset. HogPlay's Boom! Box GTS bypass clears that gate, and once it does, a Media Box or Piglet delivers wireless CarPlay, Android Auto and streaming through the batwing's speakers — no cutting, no dealer.
2021 Harley-Davidson Street Glide CarPlay & Android Auto — FAQ
Does the 2021 Harley-Davidson Street Glide support wireless Apple CarPlay and Android Auto?
Yes. The 2021 Harley-Davidson Street Glide factory Harley-Davidson Boom! Box GTS audio system supports Apple CarPlay; a plug-and-play headset HogPlay bypass unlocks it wireless, and a HogPlay Media Box or Piglet adds Android Auto, streaming and apps.
How do I get wireless Android Auto on the 2021 Harley-Davidson Street Glide?
Android Auto on the 2021 Harley-Davidson Street Glide needs CarPlay enabled first: a headset HogPlay bypass unlocks the factory Harley-Davidson Boom! Box GTS audio system, then a HogPlay Media Box or Piglet adds wireless Android Auto plus streaming apps. A bypass alone gives CarPlay; the Media Box adds Android Auto.
What apps and streaming can I run on the 2021 Harley-Davidson Street Glide?
A HogPlay Media Box turns the 2021 Harley-Davidson Street Glide into a full media center: Android Auto, Apple CarPlay plus Netflix, YouTube, maps and music. A Piglet adds wireless CarPlay and Android Auto in a smaller package.

Do I need a bypass to add Android Auto to the 2021 Harley-Davidson Street Glide?
Indirectly, yes. The 2021 Harley-Davidson Street Glide factory Harley-Davidson Boom! Box GTS audio system keeps Apple CarPlay locked, so a headset HogPlay bypass is needed first — it unlocks wireless Apple CarPlay and is the gateway to Android Auto.
