1. Dakota Digital RTX-54C-2: Best Overall
The Dakota Digital RTX-54C-2 is a top-tier digital dashboard that combines modern technology with classic compatibility. We researched its specifications and found it supports OBD-II, GPS speed, and traditional sender inputs, making it versatile for many old cars. The 5-inch TFT display is bright and readable, even in direct sunlight. Owner feedback highlights the intuitive software for customizing gauge layouts and colors. However, note that without OBD-II, you lose some data like fuel economy and diagnostic codes, so pre-1996 vehicles may not get full benefit.
This dashboard is ideal for those who want a polished, fully integrated system. But if your car lacks OBD-II and you prefer a simpler plug-and-play unit, consider a standalone GPS speedometer instead. The RTX-54C-2 is not the cheapest option, but its quality and flexibility justify the investment for many restorers.
- High-resolution 5-inch TFT screen with anti-glare coating
- Accepts signals from OBD-II, GPS, and traditional senders
- Includes turn signal and high beam indicators, dimmable backlight
Pros: Excellent customization via PC software; Works with both modern OBD-II and classic senders
Cons: Requires OBD-II for full functionality, limiting use on pre-1996 cars
2. AIM MXS 1.2: Best for Track
The AIM MXS 1.2 is a purpose-built digital dashboard for performance driving and track days. We compared its specs to others and found a 20Hz GPS module that provides smooth, accurate speed and position data. The OLED screen is extremely bright and offers wide viewing angles. Owner reviews praise its logging capabilities and rugged build. However, the 1.2-inch screen is small, and the interface can be complex for casual users. It also lacks traditional sender inputs, relying on CAN bus or GPS, which may require additional adapters for old cars.
This is best for enthusiasts who want detailed data and don’t mind a small display. Skip it if you need a large, easy-to-read speedometer for daily driving or if your car lacks CAN bus. The MXS 1.2 is a niche tool, not a universal replacement.
- Ultra-bright OLED display with 20Hz GPS update rate
- Records lap times, speed, RPM, and more with data export
- Rugged aluminum housing with IP67 rating
Pros: Exceptional data logging for track analysis; Very bright display, readable in sunlight
Cons: Small screen size may be hard to read at a glance on the street
3. Speedhut Revolution Custom GPS Speedometer: Best Customizable
The Speedhut Revolution GPS Speedometer offers unmatched aesthetic customization. We evaluated its build quality and found a stepper motor movement that is accurate and reliable. The GPS receiver locks quickly and provides real-time speed without a cable. Owner feedback highlights the ease of installation and the ability to design a unique look. However, it is a standalone speedometer, not a full dashboard. It cannot display RPM, fuel level, or other engine parameters unless you buy additional gauges. Also, GPS speed can lag in tunnels or heavy tree cover.
This is perfect for restorers who want a period-correct look with modern reliability. Skip it if you need a multi-function display or plan to integrate with engine sensors. For a complete digital dash, you would need to pair it with other Speedhut gauges.
- Choose from hundreds of face designs, colors, and bezel options
- GPS speed with no mechanical cable needed, accurate to 0.1 mph
- Includes programmable odometer, trip meter, and warning lights
Pros: Unlimited customization to match any interior; Simple GPS installation, no sensor wiring
Cons: GPS only; no OBD-II or engine data integration
4. Koso RX-2N: Best Budget Option
The Koso RX-2N is a budget-friendly digital dashboard that packs essential functions into a small package. We researched its specs and compared it to similar units: it measures speed via a wheel sensor, RPM from ignition, and includes temperature and fuel level. Owner reviews note it works well for motorcycles and small cars. However, the LCD display lacks the brightness of TFT or OLED screens, and some users report glare issues. The plastic housing feels less durable than metal alternatives. It also does not support OBD-II or GPS.
This is a solid choice for budget-conscious builders or for use in a secondary vehicle where cost matters most. Skip it if you need a premium display or plan to use it in a convertible where sunlight is a constant problem. The RX-2N is functional but not cutting-edge.
- Compact all-in-one gauge with backlit LCD
- Uses wheel speed sensor and engine tach input
- Includes shift light and programmable service interval
Pros: Affordable price for a multi-function gauge; Straightforward installation with included sensors
Cons: LCD screen can be hard to read in direct sunlight
5. Holley EFI Digital Dash 12.3-inch: Best Large Display
The Holley EFI Digital Dash is a premium, large-format display designed primarily for Holley EFI users. We compared its specs and found a 12.3-inch TFT touchscreen that is bright and responsive. It supports OBD-II and CAN bus, but its full potential is unlocked when paired with Holley’s engine management. Owner feedback raves about the clarity and customization options. However, for old cars with carburetors and no EFI, many features are irrelevant. It also requires a 12V power source and careful mounting due to its size.
This dashboard is ideal for hot rodders using Holley EFI who want a modern, integrated display. Skip it if your car is carbureted or if you prefer a simpler, smaller gauge. The large screen may overwhelm a classic dash, and the price reflects its advanced capabilities.
- Vivid 12.3-inch display with customizable layouts via touch or PC
- Direct integration with Holley EFI, also accepts OBD-II and CAN inputs
- Built-in data logging and performance analytics
Pros: Huge, sharp display with excellent visibility; Deep integration with Holley fuel injection systems
Cons: Optimized for Holley EFI; limited functionality with carbureted engines
6. AutoMeter 800045: Best Traditional Look
The AutoMeter 800045 is a GPS speedometer that looks like a classic analog gauge but uses digital technology. We researched its construction and found it meets AutoMeter’s high durability standards. The white LED backlight provides good visibility at night. Owner reviews appreciate the nostalgic look and easy installation. However, it is just a speedometer; you will need separate gauges for RPM, fuel, etc. The GPS signal can be lost briefly in tunnels, causing a temporary zero reading. Also, the bezel may not fit all dash openings without modification.
This is best for those who want to keep a classic appearance while eliminating mechanical speedometer cables. Skip it if you want a full digital dashboard with multiple readouts or if your car has a non-standard gauge opening. It is a niche product for purists.
- Classic analog-style dial with digital internals
- GPS speed with no cable, accurate and easy to install
- Programmable odometer and trip meter
Pros: Retains vintage appearance with modern reliability; Simple GPS installation, no sender needed
Cons: Single gauge only, no multi-function display
7. Racepak UDX: Best Data Logger
The Racepak UDX is a professional data logging dashboard aimed at serious racers and tuners. We evaluated its specifications and found it offers 100Hz logging across 20 channels, making it one of the most capable units on the market. The 4.3-inch TFT display is clear and customizable. Owner feedback from racing forums highlights its reliability and depth of data. However, the UDX has a steep learning curve; setup requires understanding of CAN bus and sensor wiring. It is also significantly more expensive than most options. For a casual user, many features will go unused.
This dashboard is for track enthusiasts who need detailed telemetry and are comfortable with complex installations. Skip it if you just want a simple speedometer and tach for street driving. The UDX is overkill for most old car restorations.
- High-speed data logging at 100Hz for precise analysis
- Accepts up to 20 channels including analog, digital, and CAN
- Weather-resistant housing with anti-glare screen
Pros: Professional-grade data logging and analysis; Flexible input configuration for custom sensors

Frequently Asked Questions
Can I install a digital dashboard in a car from the 1960s?
Yes, but you may need adapters. Many digital dashboards rely on OBD-II or CAN bus, which older cars lack. Look for units with GPS speed and universal sender inputs (e.g., Dakota Digital RTX). You will also need to install sensors for RPM, temperature, and fuel level. Some dashboards, like the Speedhut Revolution, are specifically designed for classic cars and use GPS for speed, making installation simpler.
Will a digital dashboard work with my existing sensors?
It depends on the dashboard. Many aftermarket digital dashboards accept standard sender inputs (e.g., 0-90 ohm fuel sender, 2000 ohm coolant temp). Check the specifications for input compatibility. Some units, like the Racepak UDX, can be configured for custom sensors. If your car uses original senders, you may need to replace them with modern equivalents or use signal converters.
How difficult is it to install a digital dashboard?
Installation difficulty varies. GPS-only speedometers (e.g., Speedhut, AutoMeter) are easiest: just mount the gauge and connect power. Full digital dashes with multiple inputs require wiring to sensors, OBD-II, and sometimes CAN bus. Some units require programming via PC or on-screen menus. If you are not comfortable with automotive wiring, consider professional installation. Most manufacturers provide detailed instructions.
Are digital dashboards legal for road use?
In most regions, yes, as long as they display speed and odometer accurately and meet local regulations. Digital dashboards must be visible and not distract the driver. Some units are DOT-approved (e.g., Dakota Digital). Check your local laws; for example, in the US, speedometers must be within a certain accuracy range. Most quality digital dashboards exceed these standards.
Do digital dashboards retain the value of a classic car?
It depends on the owner. Some collectors prefer originality, so a digital dash might reduce value. However, for daily drivers or restomods, a high-quality digital dash can be a selling point. If you keep the original parts, you can revert to stock later. We recommend choosing a reversible installation (e.g., using adapter plates) to preserve the car’s value.
Our Verdict
After researching and comparing the top digital dashboards for old cars, our top pick is the Dakota Digital RTX-54C-2 for its excellent balance of features, customization, and compatibility with both classic and modern sensors. The runner-up is the Speedhut Revolution Custom GPS Speedometer for those who prioritize aesthetics and simple GPS installation. Choose based on your car’s existing systems and your desired level of integration.
