Harley-Davidson Boom! Box 4.3
The Boom! Box 4.3 was Harley-Davidson's base touring infotainment on 2014–2018 base trims — a 4.3-inch non-touch display run by hard keys, with AM/FM, Bluetooth and a USB-A port. A good unit for its day, but it has no touchscreen and no Apple CarPlay or Android Auto, and the HogPlay GTS Bypass does not fit it stock.
Two ways to add wireless CarPlay and Android Auto: (1) swap the 4.3 for a 2019–2023 Boom! Box GTS and add a HogPlay GTS Bypass; or (2) fit an aftermarket CarPlay radio — SoundStream, Rockford Fosgate, Boss, Diamond Audio or Aquatic AV. Either way a HogPlay Media Box adds Netflix, YouTube and streaming, and a HogPlay Piglet adds Mirror Link and AirPlay.
Frequently asked questions
What is the Boom! Box 4.3?
The Boom! Box 4.3 (factory part 76000075) is Harley-Davidson’s 2014–2018 base-trim touring head unit — a non-touch display with AM/FM, Bluetooth and USB, but it was never built with Apple CarPlay or Android Auto.
Is the 4.3 in the Boom! Box the same as a touchscreen?
No — the 4.3 refers to the screen size, not touch capability; this base unit is button-and-knob controlled, unlike the larger 6.5″ GTS screen that arrived in 2019.
What part number identifies this radio?
Look for 76000075 on the unit or your build sheet — that’s the factory part number for the 2014–2018 Boom! Box 4.3 base radio.
Which years came with the Boom! Box 4.3?
Harley installed the Boom! Box 4.3 on base-trim touring models from 2014 through 2018, before the Boom! Box GTS took over in 2019.
Does my 2016 touring bike have this radio?
If it’s a 2014–2018 base-trim touring model without the larger GTS touchscreen, it likely runs the Boom! Box 4.3 — confirm with our fitment finder.
How do I know if I have the 4.3 versus the GTS?
The 4.3 is a smaller, non-touch display with physical buttons; the GTS is a larger touchscreen introduced in 2019 — check your build year and screen size against our fitment finder to be sure.
Was the Boom! Box 4.3 used on Street Glide and Road Glide models?
Yes — base-trim 2014–2018 Street Glide, Road Glide, Road King and Electra Glide models could carry the Boom! Box 4.3; check your specific build against our fitment finder.
Does the Boom! Box 4.3 have Apple CarPlay?
No. The Boom! Box 4.3 was built without Apple CarPlay — it predates Harley’s CarPlay rollout, which arrived with the 2019 Boom! Box GTS.
More questions (16)
Does the Boom! Box 4.3 have Android Auto?
No. This base radio has no Android Auto, on top of having no Apple CarPlay — it was never designed to support either.
Can I install a HogPlay GTS Bypass on my Boom! Box 4.3?
No — the GTS Bypass does not fit the 4.3 stock. A bypass only unlocks CarPlay that already exists in a radio, like the 2019+ GTS; the 4.3 has none, so there’s nothing for a bypass to unlock.
Why won’t a bypass just add CarPlay to this radio?
A HogPlay bypass reroutes an existing factory CarPlay connection — it doesn’t manufacture CarPlay out of nothing, so it can’t help a radio like the 4.3 that was never built with it.
Can I add a HogPlay Media Box directly to the Boom! Box 4.3?
Not directly — a Media Box streams through a CarPlay radio’s USB connection, and the 4.3 doesn’t have one; you’ll need a CarPlay-capable radio or a HogPlay Media Screen first.
Can I add a Piglet directly to this stock radio?
No — a Piglet adds Android Auto and mirroring through an existing CarPlay connection, which the 4.3 lacks; get to CarPlay first via an aftermarket radio, a Media Screen, or the GTS retrofit.
What’s the easiest way to get CarPlay with a Boom! Box 4.3?
Swap to an aftermarket CarPlay radio from SoundStream, Rockford Fosgate, Boss, Diamond Audio or Aquatic AV — most build in wireless Apple CarPlay right out of the box.
Can I keep my factory 4.3 radio and still get CarPlay?
Yes — a bar-mounted HogPlay Media Screen adds wireless Apple CarPlay alongside your factory radio, no swap required.
Can I retrofit my 2014–2018 bike to the newer GTS radio?
Yes — swap in a 2019–2023 Boom! Box GTS, then a HogPlay GTS Bypass unlocks its factory CarPlay and USB.
After the GTS retrofit, can I add Android Auto too?
Yes — once the GTS Bypass unlocks the new radio’s CarPlay and USB, a Piglet layers in Android Auto, Mirror Link and AirPlay mirroring.
Which aftermarket brands add native Android Auto too?
SoundStream and Diamond Audio build in native Android Auto alongside wireless CarPlay, so you get both without extra hardware.
What if I choose Boss, Rockford Fosgate or Aquatic AV?
Boss, Rockford Fosgate and Aquatic AV ship with wireless Apple CarPlay; add a HogPlay Piglet afterward for Android Auto.
Once I have a CarPlay radio, what does a Media Box add?
A HogPlay Media Box connects through your new radio’s USB to add Netflix, YouTube, YouTube Music, podcasts and SD/USB playback.
Media Screen versus a full aftermarket radio swap — which is right for my 4.3?
A Media Screen keeps your factory 4.3 in place and bolts on CarPlay fast; a full aftermarket radio replaces the head unit entirely and often adds native Android Auto too — pick based on how much you want to change.
Is the GTS retrofit worth it compared to an aftermarket radio?
The GTS retrofit keeps your Harley’s factory look and controls, while an aftermarket radio is typically faster to install and can add native Android Auto that the GTS alone doesn’t have without a Piglet.
I just want turn-by-turn directions on my rides — what’s the simplest fix?
A HogPlay Media Screen gets you wireless Apple CarPlay for maps and music without touching your factory 4.3 radio, the quickest path for most riders.
I ride a 2015 Street Glide and want the full modern setup — where do I start?
Start with an aftermarket CarPlay radio or the GTS retrofit, then layer in a Media Box and Piglet for streaming and Android Auto once the new radio’s in.
