6.5GT vs Boom! Box GTS: Why Your Harley-Davidson Touchscreen Replaceme – Cuescreens

The Harley-Davidson 6.5GT and Boom! Box GTS are two different radios, and their touchscreens are not interchangeable. The 6.5GT is the older Boom! Box system used on 2014-2018 Touring models. It has physical buttons and a plastic bezel surrounding the screen. The Boom! Box GTS replaced it starting with the 2019 model year and eliminated the mechanical buttons and plastic bezel entirely, giving the radio a flat, edge-to-edge glass face. Both screens measure 6.5 inches diagonally, which is exactly why so many riders order the wrong replacement part.

If you are shopping for a replacement touchscreen digitizer, the single most important thing you can do before checkout is confirm which of these two radios is actually in your fairing. This guide shows you how.

Why Riders Confuse the 6.5GT and the GTS

The confusion is understandable. Both systems carry the Boom! Box name. Both use a 6.5 inch display. Both live in the same spot on the same families of Touring and Trike motorcycles. From a few feet away, with the ignition off, they can look like the same unit.

Harley-Davidson itself describes the GTS touchscreen as the same size as the 6.5GT screen, with the difference being that all mechanical buttons and the plastic bezel were eliminated to create a flatscreen. That one design change is the whole story for replacement parts. The two screens mount differently, connect differently, and are built as different components. A GTS digitizer will not drop into a 6.5GT radio, and a 6.5GT screen will not work on a GTS.

There is a second layer of confusion: retrofits. Starting in late 2019, Harley-Davidson made a GTS retrofit kit available for 2014-2018 Touring models. That means there are plenty of 2015, 2016, and 2017 bikes on the road today running a GTS radio, even though those model years originally shipped with the 6.5GT or the smaller 4.3 Boom! Box. Model year alone cannot tell you which screen you need.

6.5GT vs Boom! Box GTS: The Key Differences

	Boom! Box 6.5GT	Boom! Box GTS
Original model years	2014-2018 Touring models	2019-2023 Touring and Trike models
Faceplate style	Physical buttons and plastic bezel around the screen	Flat, edge-to-edge glass with no mechanical buttons
Screen size	6.5 inches	6.5 inches
Glove use	Touch response varies	Glass designed to respond even with touchscreen gloves
Can be found on older bikes?	Standard equipment on many 2014-2018 models	Yes, via the official retrofit kit released in late 2019
Screens interchangeable?	No. Each radio requires its own screen type.

How to Identify Which Radio Your Harley Has

Three checks, in order of reliability:

1. Look at the faceplate

This is the fastest check. Walk up to the bike and look at the front of the radio. If you see physical buttons and a raised plastic frame around the display, you have the older 6.5GT. If the face is one continuous sheet of flat glass with no mechanical buttons, you have the Boom! Box GTS.

2. Use your model year as a starting point

2019-2023 Touring and Trike models equipped with the 6.5 inch touchscreen use the GTS. 2014-2018 models originally came with either the 6.5GT or the non-touch 4.3 Boom! Box radio. But remember the retrofit issue: a 2016 Street Glide with a GTS conversion needs a GTS screen, not a 6.5GT screen. The year narrows it down, but it does not settle it.

3. Verify the radio part number

The part number is the definitive answer. GTS radios compatible with the Cuescreens replacement digitizer are associated with these part numbers:

76000783
P76000783
P76000783B

Harley-Davidson radio part numbers may include suffix letters, but the main eight-digit base number is the most important identifier. Compare your original screen, radio style, connector layout, and part number before ordering.

Which Models Does the GTS Touchscreen Replacement Fit?

The Cuescreens Boom! Box GTS 6.5 inch touchscreen digitizer replacement is compatible with select 2019-2023 Harley-Davidson Touring and Trike motorcycles equipped with the 6.5 inch Boom! Box GTS system, including:

2019-2023 Street Glide and Street Glide Special models with Boom! Box GTS
2019-2023 Road Glide and Road Glide Special models with Boom! Box GTS
2019-2023 Road Glide Ultra / Road Glide Limited models with Boom! Box GTS
2019-2023 Ultra Limited models with Boom! Box GTS
2019-2023 Electra Glide Ultra Classic models with Boom! Box GTS
2019-2023 Tri Glide Ultra models with Boom! Box GTS
2019-2023 CVO Touring models equipped with the 6.5 inch Boom! Box GTS radio

Just as important, here is what it does not fit:

The older 6.5GT radio with the button and bezel style faceplate, unless the motorcycle has already been upgraded to a compatible Boom! Box GTS radio and the part number and physical screen match
The 4.3 inch Boom! Box radio
2024 and newer Harley-Davidson models with the newer infotainment screen systems, unless the radio and screen physically match this part

Why Getting This Right Matters

Ordering the wrong screen costs you time on both ends. The part arrives, it does not match your radio, and now your bike sits while a return and reorder work through the mail. If riding season is short where you live, that delay hurts more than the shipping cost.

The good news is that this is entirely avoidable. The faceplate check takes ten seconds. The part number check takes a few minutes. Do both and you will order the correct screen the first time.

What the GTS Digitizer Replacement Actually Fixes

If your Boom! Box GTS radio still powers on and the display image is visible, but the touch layer is failing, you likely do not need to replace the entire radio. The digitizer is the outer touch-sensitive glass layer that controls touch input, and it is one of the most common failure points on the 2019-2023 GTS system. Replacing just the digitizer addresses:

Ghost touches or random screen inputs
A touchscreen that stops responding or responds inconsistently
Delamination or separation of the touch surface
Bubbles under the screen
Scratches, wear, or cracked outer touch glass
Poor touch accuracy or delayed response

A digitizer replacement keeps your original radio, LCD, programming, settings, and vehicle integration in place, and no radio programming is required when replacing the digitizer on your original unit. It is not a complete radio, not an LCD, and not a fix for a black screen, no power condition, audio failure, Bluetooth issue, or navigation problem. If your display image is distorted, black, flickering, or showing lines, further diagnosis is needed before you buy anything. For a walkthrough of GTS touch symptoms and what they mean, see our guide on what to do when your Boom! Box GTS touchscreen stops working.

Note that replacing the digitizer is a hands-on repair. The radio comes out of the fairing and the old touch layer is removed and replaced, so plan for a careful, multi-step job with proper tools, or have a professional handle the installation.

Frequently Asked Questions

What is the difference between the Harley 6.5GT and the Boom! Box GTS?

The 6.5GT is the older 2014-2018 Boom! Box radio with physical buttons and a plastic bezel around the screen. The GTS is the 2019-2023 system with a flat, edge-to-edge glass touchscreen and no mechanical buttons. Both are 6.5 inches, but the screens are different parts and are not interchangeable.

Will a GTS touchscreen fit my 6.5GT radio?

No. The GTS digitizer does not fit the older button and bezel style 6.5GT radio. It only applies to an older bike if that bike has been retrofitted with a compatible GTS radio and the part number and physical screen match.

My 2014-2018 bike has a flat glass screen. What do I order?

That almost always means a GTS retrofit. Harley-Davidson released a GTS conversion kit in late 2019 for 2014-2018 Touring models, so a GTS screen may be the correct part for your bike. Verify the radio hardware part number and screen style before ordering.

What part numbers does the Cuescreens GTS screen fit?

76000783, P76000783, and P76000783B. The eight-digit base number is the key identifier, since Harley-Davidson part numbers may carry suffix letters.

Does this fit 2024 and newer Harleys?

No. 2024 and newer models with the newer infotainment screen systems use different hardware. The GTS part only applies if the radio and screen physically match the 2019-2023 GTS component.

Do I have to replace the whole radio if my touch stops working?

Usually not. If the radio powers on and the image is clear but touch is failing, the digitizer is the likely culprit, and replacing just that layer restores touch function while keeping your original radio, programming, and settings. Dealer radio replacement can be extremely expensive when the problem is only the touch screen.
