Audio Integration Interfaces for Harley-Davidson
Modern Harley-Davidson audio systems do not always provide the conventional analogue signal an aftermarket amplifier needs. On Skyline OS-equipped 2023.5 and newer Touring models, the factory audio system uses an A2B digital network, so adding aftermarket amplification requires a compatible interface to convert that digital signal into usable analogue preamp outputs.
This collection includes the NAV-TV ZEN-H and ZEN-H PRO A2B interfaces for compatible Harley-Davidson models, along with a Bluetooth receiver for systems that need a standalone wireless audio source. The right interface depends on your bike, factory audio package and the way the rest of the system is being built.
What These Interfaces Do
- Integrate factory A2B audio: the NAV-TV ZEN-H and ZEN-H PRO convert the factory digital audio signal into analogue preamp outputs for aftermarket amplifiers.
- Retain the factory head unit: upgrade the amplifier and speakers without replacing the Skyline OS infotainment system.
- Provide a proper signal path: give the aftermarket system a clean, usable source signal before amplification and tuning.
- Add DSP where required: the ZEN-H PRO combines A2B integration with onboard DSP for crossover, equalisation, level and time-alignment control.
- Add wireless audio independently: a Bluetooth receiver can provide a standalone streaming source for amplified systems that do not need factory-source integration.
FAQ
Why do I need an A2B interface on a newer Harley?
Skyline OS-equipped Harley-Davidson audio systems use an A2B digital network to carry audio through the factory system. A standard aftermarket amplifier cannot accept that digital signal directly. A compatible interface such as the NAV-TV ZEN-H converts it into analogue preamp outputs that the aftermarket amplifier can use.
What is the difference between the ZEN-H and ZEN-H PRO?
Both provide the signal conversion required to connect aftermarket amplification to a compatible A2B-equipped Harley-Davidson. The ZEN-H is suited to systems where signal processing is handled elsewhere, such as by a DSP-equipped amplifier or separate processor. The ZEN-H PRO adds onboard DSP for crossover, equalisation, level and time-alignment control.
Does the interface keep Apple CarPlay and factory navigation?
Yes. The interface works with the factory Skyline OS head unit rather than replacing it, so supported factory infotainment functions remain available, including Apple CarPlay and factory navigation where fitted or enabled.
Do all 2023.5 and newer Harley-Davidson Touring models need an A2B interface?
No. Fitment depends on the model and factory audio configuration, not simply the model year. Check the individual product fitment carefully, or contact us with your bike's year, model and current audio package before ordering.
Which amplifier do I use with an A2B interface?
Once the interface has converted the factory audio into analogue preamp outputs, it can feed a compatible aftermarket motorcycle amplifier or DSP amplifier. See our 2024 and newer amplifiers for suitable options.
