A clean, factory-style stereo solution for Road King—without adding a fairing.
The Havoc GP1 Road King Head Unit Kit is our purpose-built way to put a real stereo on a Road King while keeping the bike’s stripped, classic look intact. At the core is the Aquatic AV GP1 gauge stereo, a compact, weather-ready head unit with modern connectivity—Bluetooth streaming, USB, AUX/MP3 playback, and AM/FM radio—packaged into a setup that looks like it belongs on the bike.
Instead of a generic mount or a plastic add-on, the GP1 is installed into a billet aluminum gauge pod, then mounted to a replacement Road King nacelle cap—also billet aluminum—for a rigid, vibration-resistant install and a clean, integrated finish.
If you want Road King audio that’s compact, tough, and designed around the bike’s nacelle—this is the head unit foundation our full Havoc Road King systems are built on.
And the best part is where it lives: up on the nacelle, right in your line of sight. You can see the display at a glance, make quick adjustments without hunting around the bike, and control it easily with riding gloves on. No hidden installs, no buried controls—just a clean, integrated head unit exactly where you want it when you’re rolling.
