Android Auto, CarPlay & Streaming Apps for 2021 Harley-Davidson Street Glide
| Factory code | FLHX |
|---|---|
| Engine | Milwaukee-Eight 114 · 1,868cc / 114ci |
| Factory sound system | 6.5-inch Boom! Box GTS touchscreen |
| 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 and Android Auto — 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 and Android Auto behind a paired headset. HogPlay's Boom! Box GTS bypass clears that gate, and a Media Box or Piglet then delivers wireless CarPlay, Android Auto and streaming through the batwing's speakers — no cutting, no dealer.
HogPlay Media Boxes work on Diamond Audio, Boss Audio, Rockford Fosgate, SoundStream and Aquatic AV aftermarket radios to unlock apps, streaming and more — it's not just for factory screens. Running an aftermarket head unit? See the matching aftermarket radio pages.
