Required OEM integration kit for the SoundStream WHD14+ – keeps your factory Boom!™ amplifier working, and adds gauges and full thumb control.
The SoundStream WHD.UNLOC is the CAN bus integration kit for the WHD14+ head unit. It includes the iDataLink® Maestro® RR2 module, a plug-and-play wire harness, and the WHD14+ firmware activation. If your Harley has a factory Boom! Stage 1, Stage 2 or Harley HD Audio amplifier – which includes most CVO® models – this kit is required, not optional: without it the factory amplifier cannot communicate with the WHD14+ and your amplified speakers will not play.
On a bike with no factory amplifier, the WHD14+ is a complete upgrade on its own and the WHD.UNLOC is an optional addition for riders who want on-screen engine data and full programmable handlebar control. On a factory amplified bike it is a required part of the install. The difference is worth getting right before you order – it is one of the most common reasons a Harley head unit installation ends up with silent speakers.
Why Choose This Kit
- Keeps a factory Boom! amplifier alive – The Maestro RR2 provides two-way CAN bus communication between the WHD14+ and the Harley's factory network. That link is what allows the OEM amplifier to receive audio and control data from a non-Harley head unit. Boom! Stage 1, Stage 2 and Harley HD Audio amplifiers are retained on compatible 2014–2023 Touring models, with CVO fitment limited to early 2023 and older.
- Real engine data on screen – Up to 10 live digital gauges chosen from 40+ available parameters, subject to what your specific bike publishes on its CAN bus. On a Touring bike with a minimal factory gauge cluster, this puts the data you actually want in front of you without adding hardware to the bars.
- Warnings you don't have to watch for – Oil pressure, fuel level and engine temperature trigger on-screen pop-ups over whatever you're running, so you don't need to leave a gauge screen up to catch a problem. On a long run in Australian heat, an engine temperature alert that interrupts your map is worth more than a gauge you glance at every twenty minutes.
- Thumb controls that do the whole job – Without the kit, the included thumb control module handles volume, track skip, and call answer and end. With it, the OEM handlebar controls become fully programmable, including press-and-hold functions for scrolling, selecting, and adjusting playback and settings. Full cursor navigation from the bars means you're not reaching for the screen at speed or in gloves.
- A clean install – The supplied harness is pre-wired and plugs directly into the WHD14+'s existing loom, so no factory wiring is cut and nothing is spliced.
When the WHD.UNLOC is ordered together with the SoundStream WHD14+, MAA pre-configure the Maestro RR2 module before shipping, matched to your specific Harley model. The firmware activation is already installed and the CAN bus integration is pre-programmed, so the kit arrives ready to install – no setup, no software, no guesswork. As the authorised SoundStream dealer for Australia and New Zealand, we also provide local technical support for WHD.UNLOC installations and full WHD14+ builds.
Who It's For
Two riders need this kit. The first is anyone fitting a SoundStream WHD14+ to a Harley with factory amplified audio – most CVO Touring models, most Ultra, Limited and Tri Glide® Ultra models, and most 2014 to 2023 Touring bikes fitted with factory saddlebag or Tour-Pak® speakers. For these riders the WHD.UNLOC is mandatory equipment. The second is the rider on a non-amplified bike who wants the WHD14+ to behave like a fully integrated factory system rather than a CarPlay screen – real-time engine gauges, warning pop-ups, and thumb controls that do more than volume and track skip. For that rider it is an optional upgrade, and a worthwhile one.
This kit is for the WHD14+ only. It is not compatible with any other SoundStream head unit.

Do I Need This Kit, or Is It Optional?
It comes down to one question: does your Harley have a factory Boom! amplifier?
Yes – factory Boom! Stage 1, Stage 2 or Harley HD Audio fitted. The WHD.UNLOC is required. Without it your factory amplifier cannot be retained and the speakers it drives will not operate with the WHD14+.
No – fairing speakers only, no factory amplifier. The WHD.UNLOC is optional. The WHD14+ works as a complete head unit and audio upgrade on its own; add this kit only if you want digital gauges, warning pop-ups and advanced thumb control mapping.
Not sure which you have? Three quick checks:
1. Does it have factory rear speakers? Most bikes with factory saddlebag lid or Tour-Pak speakers have a factory amplifier as well. A bike with fairing speakers only usually does not.
2. Is it a CVO? Most CVO Touring models left the factory with Boom! Stage 1 or Stage 2 amplified audio as standard.
3. Is it an Ultra, Limited or Tri Glide Ultra? Factory amplified audio is standard or a very common factory option across these models.
Still unsure? Send Motorcycle Audio Australia your model, year and VIN before ordering and we'll confirm exactly what you need.
Firmware Updates
Once this kit is fitted, use our WHD14+ with UNLOC firmware update guide when SoundStream releases an update – not the standalone WHD14+ guide. Each SoundStream head unit setup has its own firmware and update process, and they're all listed on our SoundStream firmware updates page.
Technical Detail
System Overview
The iDataLink Maestro RR2 is the CAN bus interface module – the component that does the actual work. It sits between the WHD14+ and the Harley's data network, translating between the two so that the head unit can read vehicle data and, critically, so the factory amplifier will accept a non-Harley source. It is the same module family used for OEM integration across the automotive aftermarket, configured here specifically for Harley-Davidson Touring. On the road: this is why your factory Boom! amp still plays after the head unit is swapped – the RR2 keeps the conversation between the radio and the bike's network going.
The plug-and-play wire harness is pre-terminated for the WHD14+'s existing loom. Nothing is cut, nothing is spliced, and no factory connector is modified. On the road: a harness that plugs in rather than splices in means no crimp joints to vibrate loose over a few thousand kilometres of Australian road, and no wiring evidence if the bike is ever returned to standard.
The firmware activation is the software side of the kit – it enables the WHD14+ to recognise and communicate with the Maestro RR2. MAA install it before shipping when the kit is ordered with the head unit. On the road: the unit arrives already talking to the module, so the installer's job is mechanical rather than diagnostic.
How It Works
On a 2014 to 2023 Harley Touring bike with Boom! audio, the amplifier is not a passive device on the end of a speaker wire. It sits on the bike's CAN bus and expects to be addressed by a Harley head unit – it receives audio, but also power state, source and level information over the network. Replace the head unit with an aftermarket unit that cannot speak that protocol and the amplifier receives nothing it recognises. It does not fail gracefully to a basic input; it simply stays out of circuit, and every speaker downstream of it goes quiet.
The Maestro RR2 solves this by acting as a translator on the bus. It presents the WHD14+ to the bike in a form the factory amplifier accepts, and presents the bike's data to the WHD14+ in a form the head unit can display. This is why the fix is a module and a firmware activation rather than an adapter lead – the problem is protocol, not connector shape. It is also why there is no workaround: on an amplified bike, no amount of rewiring substitutes for the CAN bus link.
The same translation is what puts vehicle data on the screen. Up to 10 gauges can be shown at once, selected from more than 40 available parameters including oil pressure, engine temperature, gear position, battery voltage, fuel level, intake air temperature and throttle position. The exact list depends on what your specific model and year publishes on its CAN bus – an Ultra Limited and a Street Glide® of the same year do not necessarily expose the same data set, and older bikes in the range generally expose less than newer ones. On the road: battery voltage and oil pressure on screen turn the head unit into a diagnostic tool on a long ride, rather than something you only look at to change a playlist.
