Soundstream WHD.SG CarPlay Head Unit for 1998 to 2013 Batwing Touring

System Overview

Wireless smartphone integration, a 7-inch optically bonded QLCD touchscreen, a 200W Class A/B amplifier with full DSP, and OEM handlebar control all live in the one OEM-fit chassis. Here is how each part works.

Wireless Smartphone Integration and Bluetooth Audio

Apple CarPlay connects wirelessly – no cable required, no cable to wear out from vibration or weather – and once paired, your iPhone connects automatically each time you ride. Apple Maps, Google Maps, Waze, Spotify, Apple Music, podcasts, calls, and messages all appear on the 7-inch display in the CarPlay interface, controlled via touchscreen or via the integrated OEM handlebar controls. Siri® responds to voice commands for hands-free operation at speed.

Android Auto connects wirelessly the same way, bringing your Android apps to the WHD.SG's screen with no cable needed. Google Maps, Waze, Spotify, and messaging apps are all accessible from the display or via voice, and Google Assistant handles natural voice commands – directions, messages, weather, fuel stops – without taking your hands off the bars. Real-time traffic data through Waze or Google Maps keeps you on the fastest route.

Independent of CarPlay and Android Auto, the WHD.SG supports Bluetooth wireless audio streaming and hands-free phone calling. Stream music or take calls over a direct Bluetooth connection when a full CarPlay or Android Auto session isn't needed.

7" Optically Bonded QLCD Display and IPx5 Weather Resistance

The 7-inch QLCD is optically bonded – the touchscreen glass bonds directly to the display panel, eliminating the air gap that causes glare and condensation in standard screens. The result is higher contrast, better sunlight readability, and no fogging on cold mornings. The capacitive touchscreen responds accurately with gloved hands. RGB illumination on the faceplate allows the display surround to be colour-matched to the bike's lighting. Phantom buttons on the faceplate are invisible when the unit is off, appearing only when the unit is active – keeping the OEM aesthetic intact. LED indicator lights are built into the front panel using the OEM connector, maintaining the factory look through the full installation.

The faceplate is rated IPx5 – protected against direct water spray from any direction. The same optical bonding that kills glare also eliminates the internal air gap where moisture collects, silicone gaskets seal the faceplate perimeter, and sealed internals resist vibration and water ingress over the long term. Built for rain, road grime, and wash-downs.

200W Class A/B Amplifier with Full DSP

The WHD.SG includes a built-in 200W 4-channel Class A/B amplifier, 2-ohm stable – enough power to drive upgraded Street Glide and Ultra fairing speakers directly, or to serve as the head unit in a multi-amplifier build. Five-volt RCA outputs for front, rear, and subwoofer channels give downstream amplifiers a clean, strong signal. The 13-band digital equaliser includes preset staging effects and manual adjustment. High-pass crossovers cover front and rear channels independently; low-pass and subsonic crossovers cover the subwoofer output.

Installation, Camera Input and Satellite Radio

The unit mounts in the batwing fairing using the OEM hardware – no brackets, no trim panels, no modifications to the fairing required – and the OEM AM/FM radio antenna connects directly with no adapters. A 53-centimetre (21-inch) USB cable is included and can be routed to either side of the fairing for clean installation. Handlebar controls are integrated directly into the unit, so volume, track, and call functions operate from the factory bar switches without a separate handlebar control module.

An RCA video input with 12V trigger support and an on-screen shortcut allows connection of a rear or parking camera. The camera feed displays on the 7-inch screen, triggered automatically or manually via the shortcut. The unit is also hardware-ready for the SiriusXM® SXV300 vehicle connect tuner (sold separately). SiriusXM satellite radio services are not available in Australia, but the capability is present for riders who spend time in North America.
