2021 brought the touring-family displacement bump to the Tri Glide Ultra: the Milwaukee-Eight grew from 107 to 114 cubic inches under the same three-wheeled body. The trike's electronics didn't move with it — the Boom! Box GTS still runs the show from a 6.5-inch touchscreen in the batwing fairing, wired to a USB-A port in the inner fairing. That screen supports Apple CarPlay out of the box, gated behind a paired headset the factory expects to see. HogPlay's bypass removes the headset check and frees the USB, and a Media Box or Piglet then carries wireless CarPlay, Android Auto and streaming apps out through the trike's speakers — no dealer, nothing permanent.
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.

The bigger news for the 2021 Tri Glide Ultra was under the tins, not on the dash: Harley's touring range stepped up from the Milwaukee-Eight 107 to the 114, and the trike inherited the larger engine along with the rest of the family. The Boom! Box GTS radio, its 6.5-inch touchscreen, and the USB-A jack in the inner fairing all carried over untouched from the outgoing 107 bikes.
Because the radio didn't change, neither did the CarPlay situation — the GTS screen recognizes Apple CarPlay, but only after it sees a paired headset. HogPlay's bypass spoofs that pairing and opens the USB, and a Media Box or Piglet then unlocks wireless CarPlay, Android Auto and streaming through the trike's own speaker set. The work is plug-and-play and leaves nothing cut or spliced.
2021 Harley-Davidson Tri Glide Ultra CarPlay & Android Auto — FAQ
Does the 2021 Harley-Davidson Tri Glide Ultra support wireless Apple CarPlay and Android Auto?
Yes. The 2021 Harley-Davidson Tri Glide Ultra 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 Tri Glide Ultra?
Android Auto on the 2021 Harley-Davidson Tri Glide Ultra 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 Tri Glide Ultra?
A HogPlay Media Box turns the 2021 Harley-Davidson Tri Glide Ultra 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 Tri Glide Ultra?
Indirectly, yes. The 2021 Harley-Davidson Tri Glide Ultra 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.
