Havoc GP-1 HD Softail Gauge Stereo Head Unit

If you want real audio control on a Softail, it starts with a head unit you can actually see while riding and use with glove friendly controls. The Havoc GP-1 Softail Head Unit Kit puts the Aquatic AV GP-1 waterproof Bluetooth gauge stereo up where it belongs—integrated into a Havoc Motorcycles billet aluminum gauge pod and secured to your bars with a replacement billet handlebar clamp designed specifically for this setup.

The GP-1 is a proven, compact stereo with modern inputs and a rider-friendly interface. The billet Havoc pod protects it, cleans up the install, and keeps the cockpit looking intentional and 'factory feel'.  Chrome or black, to match the theme of your bike, with stylish design lines and thoughtful ergonomics - and best of all, no hidden “mystery box” Bluetooth receiver somewhere on the bike you can't see, no awkward brackets, and no fiddling with your phone on the handlebars.  It's a thoughtful, purposeful, stereo on your Softail. 

• IMPORTANT NOTE: SPEAKERS SHOW IN THE IMAGE OF THE STEREO ON THE MOTORCYCLE ARE NOT INLUDED WITH THIS COMPONENTS. FOR A KIT THAT INCLUDES SPEAKERS, GO TO THE HRS-ST-144.2HB KIT.

Installation note: Please confirm your clamp bolt pattern before ordering.

Why this kit works

• In-line-of-sight control: quick glances, quick changes—without hunting for a hidden controller

• Billet stability: rigid mounting, clean alignment, and a premium finish

• System-ready foundation: the ideal starting point for amps, speakers, and full Havoc system packages later

Why Bluetooth + SiriusXM Streaming + USB + AM/FM Is the Sweet Spot

This is the “have it all” setup: stream when you want, play offline when you need, and always have broadcast radio as a backup, without juggling extra boxes.

• Bluetooth + SiriusXM app = endless choice. Run the SiriusXM app (or Spotify/Apple Music) from your phone for stations, playlists, and discovery—clean, simple, and always updated.

• USB stick = zero-signal reliability. Load a USB drive with your favorite music and you’ve got instant playback even when cell service drops.  No buffering, no dead zones, no drama.

• AM/FM = always-on fallback + local info. When you just want something playing, or you need local weather/traffic/news, broadcast radio is still the most dependable “it just works” option.

Bottom line: you get premium streaming, offline backup, and old-school reliability, so your music doesn’t depend on one fragile link in the chain.

Choosing the right option

Softails aren’t one-size-fits-all, so this kit is offered with two handlebar clamp bolt patterns. You simply select the one that matches your setup (see the info-graphic picture above):

• Parallel bolt holes, or

• Offset bolt hole pattern

After that, pick the finish that matches your bike. The billet pod and clamp are available in Black or Chrome, so the kit can disappear into a darked-out cockpit or pop on a bright build.
