Head Units for the Harley-Davidson Tri Glide® Ultra (2014–2025)
Head-unit options for Harley's trikes follow the same rules as the two-wheel Touring range, decided by model year. The Tri Glide® Ultra is a faired batwing trike, so its head-unit options match the equivalent batwing bike for each year. Pre-2014 trikes use a conventional radio aperture, and the 2014 to 2025 Tri Glide Ultra runs the factory Boom! Box radio — the trike kept that architecture for its whole production run, two model years longer than the two-wheel Street Glide and Road Glide. Skyline OS reaches the trike range in 2026, on the Road Glide 3 and the Street Glide 3 Limited.
What is Different on a Trike
For a 2014 to 2025 Tri Glide, the same wireless CarPlay head units used on the 2014 to 2023 batwing apply, so see the 2014 to 2023 batwing head units. On the 2026 Skyline OS trikes, a direct head-unit swap is impractical, so the practical path is to keep the factory unit and add amplification through a compatible A2B interface. The real trike-specific gain is tuning: the longer distance from the front stage to the rear listening position makes a DSP with time alignment more audibly worthwhile than on a two-wheeler.
FAQ
What head unit fits a 2014 to 2025 Tri Glide?
The Tri Glide® Ultra is a faired batwing trike on the Boom! Box radio for its whole 2014 to 2025 run, so the same wireless CarPlay head units used on the 2014 to 2023 batwing apply. See the 2014 to 2023 batwing head units.
Can I replace the head unit on a 2026 Skyline OS trike?
Not practically. Skyline OS makes a direct aftermarket swap difficult, as on the two-wheel models. The practical path is to keep the factory unit and add amplification through a compatible A2B interface such as the NAV-TV ZEN-H. This applies to the 2026 Road Glide 3 and Street Glide 3 Limited, not to the 2024–2025 Tri Glide Ultra, which is still Boom! Box.
Does a trike benefit from a DSP?
Yes, and it can be even more beneficial than on a two-wheeler. The longer distance from the front stage to the rear listening position makes time alignment more audibly significant, so a DSP earns its place in a trike build.
