GPS Speedometer for Classic & Vintage Cars
Add an extra speed display to your classic with an iPhone and a suitable removable mount. Keep the original dashboard intact and record your drives.
Why Classic Car Speedometers Fail
Cable-Driven Systems
Mechanical cables and connections can wear or break. Parts availability depends on the vehicle and the components that need repair.
Worn Internal Gears
Wear inside a mechanical gauge can affect needle movement. Have inconsistent or stuck readings checked to identify the cause.
Restoration Cost
Restoration cost, parts availability and turnaround vary by instrument, vehicle and specialist. Ask for a quote after the fault has been assessed.
Preserve Your Classic's Originality
A suitable removable phone mount lets you add a GPS display without rebuilding the dashboard or connecting to the original speedometer.
No Drilling
Suction-cup, vent, or air-mount. Zero holes in your dashboard, zero permanent changes.
No Wiring
The app does not connect to the vehicle’s speed sensor or wiring. Follow the instructions for your phone mount and charger.
Fully Reversible
Pop the mount off when you sell, show, or store the car. The original speedo stays original.
Perfect for Classic Car Enthusiasts
Car Shows & Cruises
- Drive to the show without speedo guesswork
- Quick removal for static display
- No permanent installation = judges-friendly
Restoration Projects
- Add a supplementary display during a restoration project
- Compare the GPS estimate and the vehicle display under steady, clear-sky conditions. A difference can come from either measurement; it does not by itself identify a fault or prove which instrument is correct.
- Use the app as a supplementary speed display while arranging a repair. It does not replace required vehicle equipment; check the rules that apply to your vehicle.
Verification & Calibration
- Compare the GPS estimate and the vehicle display under steady, clear-sky conditions. A difference can come from either measurement; it does not by itself identify a fault or prove which instrument is correct.
- Compare readings after a tire-size change
- GPS speed does not use wheel rotation or a tire-size setting. It still depends on usable location data.
Test Drives & Sales
- Buying a classic? Quick GPS speed check
- Compare the GPS estimate and the vehicle display under steady, clear-sky conditions. A difference can come from either measurement; it does not by itself identify a fault or prove which instrument is correct.
- Core GPS speed tracking and trip recording work without internet, with location permission and a usable GPS signal. Automatic road-speed-limit data and weather need internet. Maps and other connected features may be unavailable offline.
Daily Vintage Driver
- Use an additional speed display on everyday journeys
- Compare your speed with posted limits
- Core speed and trip recording work offline with a usable GPS signal.
Vintage Racing
- Track speed during open-track events

Non-Permanent Mounting Options
Windshield Suction
Standard windshield suction mount — adjustable, quick to remove, leaves no marks.
Vent Mount
Air-vent clip mount — works on most vehicles from the late 1980s onward. Note: pre-1980s vents often have horizontal slats that don't grip modern phone clips well; if your car is 1970s or earlier, prefer suction or dash-pad mounts.
Dash Pad
Non-slip silicone pad on the dashboard — phone sits flat, can be removed in seconds without residue.
Cup-Holder Mount
Goose-neck arm anchored in the cup holder — most adjustable position, fully removable.

GPS provides an estimate of speed over ground, independent of wheel size. Signal quality, obstructions, low speed and processing can affect the reading. A fixed percentage error or greater accuracy than another instrument is not guaranteed.
Yes — that's the whole point. Suction mount, vent mount, or dash pad — zero modifications, zero drilling, zero wiring. Fully reversible in seconds.

Tracking stops when the phone powers off. Charge it, reopen the app and check the last saved trip before starting another recording. Battery use varies with the device, battery health, screen brightness, signal and enabled features. No fixed hourly drain or runtime has been established for the app. For long trips, plan a suitable charger or power bank.
Allow time for a usable location reading and keep a clear view of the sky. Acquisition time varies with the device and surroundings; there is no fixed waiting time.
