The MSHD14 is Diamond Audio's Plug N-Play Digital Media Receiver for 2014-2023 Harley-Davidson touring motorcycles. It replaces the factory radio.
It is built around an internal Maestro RR2 CANBUS interface, which Diamond Audio calls a first for a motorcycle head unit, and adds six programmable auxiliary triggers for switching lighting and accessories from the screen or the handlebar controls.
What HogPlay adds to your MSHD14
Your MSHD14 already does wireless CarPlay and Android Auto, so you don't need us for that. What it can't do is stream: a HogPlay Media Box adds Netflix, YouTube and other apps straight to the screen that's already on your bike.
A USB Piglet adds Mirror Link and AirCast screen mirroring — putting your phone's actual screen on the dash, which no head unit does on its own.
A bypass adaptor doesn't apply to a Diamond Audio unit: a bypass unlocks a factory CarPlay radio, and yours has already replaced it.
What each part does
USB Piglets
A USB Piglet plugs into the head unit's USB port and adds Mirror Link and AirCast screen mirroring — mirroring your phone's actual screen to the dash, which no head unit does on its own.
Media Boxes
A Media Box adds Netflix, YouTube and other streaming apps to the MSHD14, running them on the screen you already have.
Why there's no bypass adaptor here
A bypass adaptor unlocks a factory CarPlay head unit. Once a Diamond Audio MSHD14 is installed there's no factory radio left to unlock — the MSHD14 already does CarPlay itself. What HogPlay adds on top is screen mirroring and streaming, not activation.

Frequently asked questions
What exactly is the Diamond Audio MSHD14?
The MSHD14 is Diamond Audio’s Plug-N-Play digital media receiver built to replace the factory radio on 2014–2023 Harley-Davidson touring models, with a 7″ 1000 NIT glove-friendly touchscreen and native wireless Apple CarPlay and Android Auto built in from the factory.
Is the MSHD14 screen actually visible in direct sunlight?
Yes — the MSHD14 runs a 1000 NIT panel, roughly double a typical car stereo, so it stays readable at highway speed in full sun and still responds to touch with riding gloves on.
Which motorcycles does the MSHD14 fit?
The MSHD14 is built specifically for 2014–2023 Harley-Davidson touring models — Street Glide, Road Glide, and Ultra variants — before the 2024+ Skyline platform change.
Will the MSHD14 fit my 2019 Street Glide?
Yes — a 2019 Street Glide falls squarely in the MSHD14’s 2014–2023 touring fitment window, so it’s a direct Plug-N-Play swap for your factory radio.
I ride a 1998–2013 Road Glide — is this the right unit?
Not this one — the MSHD14 covers 2014–2023 touring bikes. For a 1998–2013 Road Glide, look at the Diamond Audio MSHD9813RG instead.
I ride a 1998–2013 Street Glide — is this the right unit?
Not the MSHD14 — that’s built for 2014–2023 touring bikes. For your era, the Diamond Audio MSHD9813SG is the correct match.
Does the MSHD14 work on a 2024 or newer Road Glide?
No — 2024+ touring models run Harley’s Skyline digital bus, which the MSHD14 and every other aftermarket drop-in unit can’t interface with. Not sure which year you have? Run your bike through the fitment finder to confirm.
Not sure which Diamond Audio unit matches my bike?
Run your year, make, and model through the fitment finder, or browse the full lineup on the Diamond Audio brand hub — it’ll point you to the MSHD14, MSHD9813RG, or MSHD9813SG as needed.
More questions (19)
Does the MSHD14 support Apple CarPlay?
Yes — the MSHD14 has native wireless Apple CarPlay built directly into the head unit, no dongle, bypass, or extra part required.
Does the MSHD14 support Android Auto too?
Yes — unlike CarPlay-only aftermarket radios, the MSHD14 has native wireless Android Auto built in alongside CarPlay, so either phone connects wirelessly right out of the box.
Do I need a bypass module for CarPlay or Android Auto on the MSHD14?
No — the MSHD14 replaces your factory radio outright and already has both CarPlay and Android Auto built in, so there’s no bypass or extra module to buy for either one.
What does a HogPlay Piglet add on top of the MSHD14?
A HogPlay Piglet adds Mirror Link and AirCast/AirPlay screen mirroring to the MSHD14 — casting your phone’s full screen to the 7″ display, which isn’t part of native CarPlay or Android Auto on any head unit. Browse Piglet adaptors.
Can I mirror my whole phone screen on the MSHD14, not just CarPlay apps?
Not natively — CarPlay and Android Auto only project their own app tiles. Add a HogPlay Piglet to the MSHD14 for true full-screen mirroring and AirPlay.
What does a HogPlay Media Box add on top of the MSHD14?
A HogPlay Media Box adds apps the MSHD14 doesn’t run on its own — Netflix, YouTube, YouTube Music, podcasts, and streaming, plus SD-card and USB-drive media playback. See the Media Box lineup.
Can I watch Netflix or YouTube on the MSHD14 while parked?
Not through CarPlay or Android Auto alone — those are driving-focused platforms. A HogPlay Media Box paired with the MSHD14 unlocks full streaming apps for camp or downtime.
Is the MSHD14 really plug-n-play, or does it need custom wiring?
It’s Plug-N-Play — the MSHD14 uses the internal iDatalink Maestro RR2 interface to tie into your Harley’s existing harness, so there’s no custom splicing to get it running.
Will installing the MSHD14 kill my factory gauges or steering-wheel controls?
No — the built-in Maestro RR2 CANBUS interface on the MSHD14 retains your factory gauges and handlebar controls, so switching to the new head unit doesn’t break anything else on the dash.
What is the Maestro RR2 interface Diamond talks about with the MSHD14?
The Maestro RR2 is an iDatalink CANBUS interface built into the MSHD14 — Diamond calls it a first for a motorcycle head unit — that lets the new radio talk to your bike’s factory electronics instead of just bolting on top of them.
What are the six auxiliary triggers on the MSHD14 for?
The MSHD14 gives you six programmable auxiliary triggers to switch accessory lighting or other add-ons directly from the touchscreen or your handlebar controls, no separate switch panel needed.
What audio tuning options does the MSHD14 have?
The MSHD14 runs a 10-channel DSP with time delay and crossovers, giving you real tuning control over your Harley’s speaker setup instead of a flat factory EQ.
Is the MSHD14 weatherproof for riding in the rain?
Yes — the MSHD14 carries an IPX6 rating, built for the weather exposure of an open-air motorcycle install rather than a car dash.
What Bluetooth version does the MSHD14 use?
The MSHD14 runs Bluetooth 5.2 for phone calls and audio streaming, on top of its native wireless CarPlay and Android Auto.
How is the MSHD14 different from my Harley’s factory infotainment?
The factory head unit on a 2014–2023 touring bike doesn’t offer native wireless CarPlay and Android Auto together; the MSHD14 replaces it with both built in, plus a tunable 10-channel DSP and a brighter 1000 NIT screen.
What’s the difference between the MSHD14 and the MSHD9813RG or MSHD9813SG?
All three share the 7″ 1000 NIT screen, 10-channel DSP, IPX6 rating, and Bluetooth 5.2, but they fit different eras: the MSHD14 is 2014–2023 touring with Maestro RR2 and six aux triggers, while the MSHD9813RG and MSHD9813SG are built for 1998–2013 Road Glide and Street Glide respectively.
How does the MSHD14 compare to CarPlay-only aftermarket radios?
Brands like Aquatic, Boss, or Rockford Fosgate typically ship CarPlay-only, leaving Android riders without wireless projection. The MSHD14 has both native wireless Apple CarPlay and native wireless Android Auto, so either phone works without an add-on.
I ride with a buddy who has an Android phone and I have an iPhone — does that matter for the MSHD14?
Not on the MSHD14 — it runs native wireless Apple CarPlay and native wireless Android Auto side by side, so whichever bike you’re on, your own phone connects the same way.
I want to screen-record or cast video for group rides — does the MSHD14 handle that on its own?
Not out of the box — CarPlay and Android Auto only show their own apps. Add a HogPlay Piglet to the MSHD14 for AirPlay/Mirror Link screen casting, or a Media Box for streaming apps and offline USB media on long tours.
Ride safe: on-screen video is for parked viewing only — never watch video while the motorcycle is in motion. Music, audio and navigation are made for the road.
