Product Description
Soundstream Reserve EPS-MRR iDataLink Maestro RR with Waterproof Enclosure (14SI and V2 Only) - Precision Power
The Precision Power EPS-MRR is the smart way to connect your Harley-Davidson to a HDHU.14Si or V2 radio. It keeps your factory handlebar controls working and lets your gauges display through the radio, so everything stays connected and easy to control.
If you’re upgrading your audio system, this module helps your bike and radio work together without losing important features.
Made for 2014–2023 Harley-Davidson Models
The Precision Power EPS-MRR communicates directly with the Harley-Davidson Can-Bus system on 2014 through 2023 models. That means your bike’s electronics stay in sync with your new radio.
For CVO Boom 1 and Boom 2 systems, you’ll need the BIN number from the factory radio during programming. This allows the Maestro software to power the system on properly.
To prevent Can-Crash issues, make sure to select “Gauge on Demand” in the settings.
Built for HDHU.14Si and V2
The Precision Power EPS-MRR is specifically designed to pair with the HDHU.14Si or V2. When connected, you keep your handlebar controls and integrate your gauges into the radio display.
It’s a direct and focused solution—no extra features, just what’s needed for proper integration.
Waterproof Protection Included
Motorcycles face rain, heat, and vibration. That’s why the Precision Power EPS-MRR comes with a waterproof enclosure. It helps protect the Maestro module from the elements, giving you added reliability on the road.
