Where this fits in the build
Vehicle-specific and open-air equipment should be chosen around fitment, environment, placement and the output needed where the system will actually be used.

ARC Audio PSM-Pro + Maestro AR Harley-Davidson DSP Integration Package
On a 2014–2023 Harley bagger, the factory radio can stay in the bike and still feed a serious aftermarket system. The problem is getting away from the factory-shaped audio signal before you start tuning around it. ARC’s PSM-Pro + Maestro package does that by combining the compact PSM-Pro DSP with an iDatalink Maestro AR module and an aHD2 vehicle harness so the factory GT/GTS radio can remain in place while the system gets a flat signal path into the DSP.
This is the integration route for the rider who wants to keep the factory radio, controls and factory-style operation instead of replacing the head unit just to get a usable signal. Once the Maestro side is flashed and the system is connected, the PSM-Pro becomes the tuning point for the aftermarket audio system rather than spending DSP resources trying to undo the factory radio’s processing.
What the package includes
- ARC Audio PSM-Pro compact DSP
- iDatalink Maestro AR amplifier-replacement module
- iDatalink Maestro aHD2 Harley-Davidson plug-and-play harness
Where this path makes sense
- 2014–2023 Harley-Davidson bagger applications using the supported factory GT/GTS radio architecture
- Systems keeping the factory radio but replacing or expanding the factory amplifier/speaker system
- ARC Audio motorcycle systems that need real DSP control after the factory signal has been corrected
The advantage here is not simply that the parts plug in. The Maestro module stays in the bike, so the corrected integration path stays with the system instead of depending on a one-time radio flash that can later be lost or changed. ARC specifically positions this package as the cleaner signal route when keeping the factory GT/GTS radio.
Maestro package vs. the newer Zen-H path
These are not interchangeable Harley solutions. This Maestro/aHD2 architecture belongs with the earlier GT/GTS-era baggers. ARC separately identifies the PSM-Pro + NAV-TV Zen-H route for the newer 2023.5+ Road Glide and Street Glide audio architecture. On transition-year bikes, confirm the exact radio and factory amplifier system before ordering rather than choosing by model year alone.
What this package does not include
This is the DSP and factory-integration package. Amplification, speakers, amplifier power wiring and any model-specific mounting hardware are separate unless they are part of a larger ARC motorcycle system package.
Fitment note: iDatalink application coverage varies by exact Harley model and factory radio configuration. Verify the motorcycle and radio before installation, especially on 2023 transition applications.
