Grundig
Founded in 1945 in Germany by Max Grundig, Grundig advanced automotive electronics. After being acquired by Delphi Technologies in 2003, it expanded to North America and is now owned by Germany’s THS, integrating German engineering with American automotive knowledge.
As a global mobility solutions provider, Grundig Auto supplies ebikes, high-quality audio systems, and vehicle components using European technology and global production networks.
Product Overview
The Grundig Mini HUD lifts your Tesla's key driving data up to eye level, so you can read your speed and safety alerts without dropping your gaze to the center touchscreen. Precision-molded for Model 3 (2019–2023) and Model Y (2021–2024), it tucks cleanly into the dash and plugs straight into the factory 26-pin rear OBD port — no cutting, no wire splicing, and no permanent change to your vehicle.
Key Features
- Drive Safer, Focus Forward: Positioned right in your natural line of sight, allowing you to check speed and driving gear without looking away at the center screen.
- Ultra-Slim 1.8cm Profile: Designed to fit seamlessly inside the Tesla air vent gap. No ugly mounts, no blocked air conditioning, and no exposed messy cables.
- Instant Speed Synchronization: Features a pure numerical LED/LCD display that instantly mirrors your Tesla center screen in real-time. Automatically aligns with your car's speed setting (MPH or KM/H) with zero setup required.
- Essential Vehicle Alerts: Displays real-time speed, current gear (P/R/N/D), turn signals, battery percentage, seatbelt, and door-open warnings.
- No Double-Images or Glare: Unlike traditional windshield projection HUDs that suffer from blurry reflections, this built-in high-contrast display provides crisp, clear readings day or night.

Frequently Asked Questions
Which Tesla models is this HUD display compatible with?
It fits Tesla Model 3 (2019–2023, excluding the 2024 Highland refresh) and Model Y (2021–2024). It connects directly to the factory 26-pin rear OBD/CAN-bus port — please confirm your vehicle has this port before placing an order.
Does the display show mph or km/h?
The display shows the speed number only — no mph or km/h text is printed on the screen. The numerical value synchronizes automatically with your Tesla's native center screen setting in real time, matching whichever unit your vehicle is set to display.
What information does the display show?
The high-contrast multi-color LCD displays your real-time speed, battery percentage, current gear position (P/D/R/N), turn-signal arrows, and essential safety alerts (seatbelt reminder, door open alert, and low-battery warning).
How is the display powered?
It draws 12V power directly from the factory 26-pin rear OBD connector via the included plug-and-play wiring harness. No separate power supply, batteries, or hardwiring are needed.
Do I need to remove the center screen or disassemble the dashboard?
No. The installation is fully concealed and non-destructive. It mounts seamlessly in the air vent and accesses the rear OBD connector without requiring you to remove the center touchscreen, cut wires, or alter your vehicle's original interior structure.
