Soundstream SG.V2 CarPlay Head Unit for 1998 to 2013 Batwing Touring

System Overview

The SG.V2 combines wireless smartphone integration, an 8.3-inch daylight-readable touchscreen, built-in navigation, wireless headset and group-ride audio, and a full DSP amplifier stage in one IPx5 water-resistant receiver. On 2009–2013 models an iDataLink Maestro RR2 module adds two-way communication with the motorcycle, unlocking digital gauges, advanced handlebar control programming, and factory Harman/Kardon amplifier retention.

Smartphone Integration and the 8.3-inch Display

Apple CarPlay and Android Auto both connect wirelessly – no cable required, and no cable to damage from vibration or weather. Once your phone is paired it connects automatically each time you ride, and the 8.3-inch display becomes an extension of it: Apple Maps, Google Maps, Waze, Spotify, Apple Music, podcasts, messaging apps, calls, and messages, in interfaces designed for single-glance operation. Control everything via touchscreen or via the OEM handlebar controls. Siri® responds to voice commands for hands-free operation at speed, and Google Assistant handles natural voice commands on the Android side – ask for directions, send a message, or find the nearest fuel stop 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 SG.V2 also supports standard Bluetooth audio streaming, playback control, and hands-free calling – for when a full CarPlay or Android Auto session isn't needed.

The 8.3-inch widescreen Quantum QLCD touchscreen runs at 1000 NITs – bright enough to remain clear in harsh Australian sunlight, with wide viewing angles and fast touch response. Maps, gauges, and menus are readable at a glance without leaning in, and the larger-than-OEM screen makes a real difference on long rides where you're checking navigation frequently. Night brightness adjusts automatically so the display doesn't blind after dark.

Vehicle Integration – Gauges, Controls and Factory Amplifier Retention (2009–2013)

With an iDataLink Maestro RR2 module connected (sold separately, 2009–2013 models), the SG.V2 gains two-way communication with the Harley's CAN bus. Up to 10 real-time digital gauges are displayed on screen – choose from more than 40 available parameters including oil pressure, engine temperature, gear position, battery voltage, and fuel level, subject to the data available from your specific bike. Pop-up alerts notify you of critical readings without watching the gauge screen continuously. OEM handlebar thumb controls are retained and fully programmable for scrolling, selecting, and adjusting playback and settings, including press-and-hold functions not available in basic mode. The wiring harness is pre-configured for Maestro RR2 connection. Gauge functionality via Maestro RR2 is not available on bikes fitted with a ThunderMax ECM; amplifier retention is unaffected.

That same CAN bus connection is what allows the SG.V2 to retain the factory Harman/Kardon Boom! Audio amplifier on supported 2009–2013 Street Glide, Electra Glide, Ultra, and CVO models when an iDataLink Maestro RR2 is fitted. The reason this matters is in how that amplifier is switched on. The MTX factory amplifier uses a more conventional turn-on arrangement and could already be retained by the SG.V2 without a module. The Harman/Kardon amplifier doesn't work that way – it waits for a digital turn-on command on the motorcycle's CAN bus, sent by the factory Harman/Kardon head unit. Remove that head unit and the amplifier never switches on, regardless of what is wired to it. Retaining it requires a radio that can communicate on the CAN bus and issue that command, which is why it depends on Maestro integration. SoundStream Reserve describes this as an industry first for the platform.

For a supported 2009–2013 CVO or Ultra, this means the head unit can be upgraded without immediately removing the factory amplifier, replacing all of the speakers, or rewiring the Tour-Pak system. The SG.V2 also gives you tuning control the factory radio never offered – the equaliser and crossovers described below – which may help improve the result from a factory system that is still in good condition. Retention data is currently published for 2009 and newer factory amplifiers only; on 1998–2008 bikes with a Harman/Kardon amplifier, the factory amplifier must still be bypassed and replaced.

Built-in Navigation

The SG.V2 includes iGo Primo GPS navigation with a magnetic mount GPS antenna, operating independently of mobile coverage – useful where data is unreliable or unavailable. Australian maps are not pre-loaded; maps and points of interest for Australia are available for purchase and annual update through Naviextras.com. For most Australian riders, Apple Maps or Google Maps via wireless CarPlay or Android Auto provides a more current and more detailed navigation experience, and the built-in iGo system is the backup when your phone isn't an option.

Wireless Headsets and Group Riding

The SG.V2 connects directly to OEM and aftermarket Bluetooth headsets and helmets without a Harley WHIM module – simplifying installation and removing a common point of failure. Pair up to two headsets simultaneously, covering rider and passenger. Configure the headsets to receive GPS navigation prompts, music, or both, so you're not fighting navigation call-outs over the music at volume.

Rally Mode turns the SG.V2 into a broadcast hub for your group ride. Stream your playlist to up to 300 riders within 100 metres (330 feet) – all riding to the same music simultaneously. Riders with Rally Mode-equipped head units or accessories pair to the principal broadcaster's stream; the broadcaster controls the music, paired riders listen in. There's no limit on the number of users who can pair to a single broadcaster.

Amplification, Tuning and Expansion

The built-in 200W peak 4-channel Class-D amplifier is 2-ohm stable – enough clean power to drive high-performance fairing and bag 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 more signal to work with, reducing noise at high volume. The 15-band digital equaliser includes preset and custom settings. High-pass crossovers operate independently for front and rear channels; low-pass and subsonic crossovers cover the subwoofer RCA output. When you're ready to move past a retained factory amplifier, those 5V outputs mean the head unit won't become the weak link in the system.

Camera Input, Weather Sealing and Satellite Radio

An RCA video input with 12V trigger support and an on-screen shortcut allows connection of an aftermarket rear-view or reverse camera. The feed displays on the 8.3-inch screen, triggered automatically on reverse or manually via the shortcut. It pairs directly with the HD Vision UltraV2 rear camera.

The SG.V2's faceplate is rated IPx5 – protected against direct water spray from any direction. Built for long-term use in real riding conditions: rain, dust, and wash-downs included. 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.
