BOLTHUT™ GPS HUD Speedometer — Big Digital Speed Display, USB Plug-In
Why Drivers Add the BOLTHUT™ HUD
Six reasons this little display earns its dash space.
Speed Up High
Big digits sit up where a quick glance catches them.
Clear in Sunlight
Readout stays readable at noon and gentle on eyes at night.
Stick, Plug, Done
One adhesive pad and a USB plug — no tools, no wiring.
No OBD-II Needed
GPS does the reading, so older trucks and RVs are in.
On and Off Itself
Powers up with the car and shuts down when you park.
Your Unit, Your Color
Order MPH or km/h with white or green digits.
Couldn't load pickup availability
Product Information
A big GPS speed readout that installs in minutes. Stick the pad on the dash, plug the USB cable into a port, and large LED digits report your speed in real time — crisp in direct sun, gentle on the eyes after dark.
GPS does the measuring, so it works in older trucks, RVs, rentals, and lifted builds on resized tires — no OBD-II port, no wiring, no menus. Pick the MPH or km/h face in white or green at checkout, and it arrives reading exactly what your road signs say.
Buying it for Mom or Dad? Setup is a pad and a plug, any driver can read it, and if it's not the right pick there's a 30-day return.

Does This Sound Familiar?
Straight from drivers who ended up plugging one of these in:
If any of these hit home, a plug-in readout is the simple fix.
Why Other Fixes Fall Short
OBD-II Plug-In Displays
They only fit newer OBD-II cars — and leave a cord tied up at your knees.
Windshield Projection HUDs
The floating glow washes out in daylight unless you stick a film on your glass.
Phone Speedometer Apps
They tie up your screen and drain the battery before the drive ends.
Multi-Function GPS Gauges
Menus and modes bury the one number you actually wanted.
Each one gets close — none just puts a big clean number where you look.
Buy Once, Skip the Re-Buys
Three ways drivers put a speed readout on the dash:
Buying the flashing no-name twice costs more than one display that just reads your speed.
Aftermarket accessory. Not affiliated with, endorsed by, or sponsored by any vehicle manufacturer; brand names used for compatibility reference only. Always check fitment for your exact year/make/model before purchase.
Why the BOLTHUT™ HUD Actually Works
Each piece answers one of those dash headaches above.
GPS Speed Feed
Satellites report your speed — no cable to the engine.
Big LED Digits
A number you catch without leaning in or squinting.
Stick-On Pad
Plants on the dash and stays put over bumps.
Hidden Cable Run
The long USB lead tucks around the console edge.
Auto Power
Wakes with the ignition, sleeps when you park.
Palm-Size Housing
About 3 in wide — it doesn't crowd the dash.
Plug it in once, and the number is simply there every drive.
Your Speed, In Your Line of Sight
No menus, no wiring — a GPS readout that starts working the day it arrives.
Stick the pad on the dash, plug into USB, and large LED digits report your speed in real time.
- Plug-in
- GPS-driven
- Fits most rides
Digits You Can Read at Noon
The LED panel holds its own in direct sun — no cupping a hand over the dash to check your speed.
Sun-readable
Alex J. calls it incredibly bright and easy to read, even in direct sunlight.
After dark it stays gentle on your eyes.
- ↳ Direct sun
- ↳ Night-friendly
- ↳ Big segments
Speed From Satellites, Not the Engine
GPS does the measuring, so a worn cluster, resized tires, or a km/h dash can't skew what you see.
GPS-driven
Michael C. checked it against his phone's GPS and calls the reading very accurate on his older car.
One readout for the truck, the RV, or the rental.
- ↳ No OBD-II
- ↳ Older cars
- ↳ Big-tire builds
Stuck On and Plugged In — That's It
Press the adhesive pad onto the dash, run the USB cable to a port, and you're reading speed.
No tools
Emily C. sums it up in five words: simple plug and play, holds well.
The long cable tucks away so nothing dangles.
- ↳ Adhesive pad
- ↳ USB power
- ↳ Tidy cable
It Runs Itself After That
Plugged into a switched port, it wakes with the ignition and goes dark when you shut off.
Auto on/off
David M. set one up for his dad and calls the automatic power on and off a nice touch.
Nothing to remember on the way out of the driveway.
- ↳ Wakes with car
- ↳ Sleeps parked
- ↳ Zero upkeep
Designed for the Quick Glance
Small touches that keep the number clear and the dash clean.
LED Digit Panel
Segments sized to read in a blink, day or night.
GPS Inside
Finds satellites on its own — no wiring into the car.
USB Power
Runs off the port your car already has.
Low-Profile Base
The adhesive pad plants it flat and low on the dash.
One Readout, Many Rides
Dim or Tired Clusters
Big digits stand in when the factory needle fades or quits.
Lifted & Resized
GPS reads the true road speed bigger tires throw off.
km/h Dashboards
Order the MPH face and skip the mental math.
Take It Along
Light and USB-powered — it moves to the RV or rental with you.
SETUP
On Your Dash in Four Steps
Pick the Spot
Choose a flat spot low on the dash where it won't block your view.
Stick the Pad
Press the adhesive pad down firmly on a clean surface.
Plug Into USB
Use a port that switches with the ignition so it powers itself.
Tuck and Drive
Route the cable around the console, start the car, and the digits light up.
From Dim Needle to Big Digits
My older car's speedometer is a bit dim and hard to see at night. This digital display solved that problem completely. The speed reading is very accurate compared to my GPS.
The number you need, without looking down
Your eyes stay up, on the road, where they belong.
