GRUNDIG: 80 Years of Automotive Engineering & Precision

Since 1945, Grundig has stood for German precision engineering. From the 1951 Autosuper 248 to today, we've evolved from car audio to advanced automotive safety solutions. This heritage drives our TPMS systems: professional-grade components and real-time sensing technology that deliver reliable monitoring for every vehicle — from city cars to outback touring rigs.

Ⅰ. Compatible Vehicles

Supporting seamless switching between 4, 6, and 8-wheel modes with a heavy-duty range up to 116 PSI (8.0 Bar):

Campervans & Motorhomes: Engineered for diverse motorized builds, including popular chassis such as the built on the chassis Australians and Kiwis actually drive: Mercedes-Benz Sprinter, Fiat Ducato, Ford Transit and VW Crafter.

Caravans, Camper Trailers & Pop-Tops: Tailored for a vast array of towable units, from lightweight single-axle campers to premium tandem-axle tourers from Jayco, New Age, Avan, Coromal and Crusader.

Fifth Wheelers: Optimized for high-pressure setups under 110 PSI, ensuring reliable data sync for Optimised for high-pressure setups under 110 PSI, with reliable data sync for fifth wheelers and multi-axle rigs — a growing segment of the Australian touring scene.

4WDs, Utes & Tow Vehicles: Designed for powerful towing vehicles and adventure-ready rigs, including icons like the including Australia's favourite towing rigs: Toyota LandCruiser 70 & 300 Series, Hilux, Ford Ranger, Isuzu D-MAX and Nissan Patrol — plus RAM 1500/2500 for heavy towing up to 4.5 tonnes.

Ⅱ. Product Function

【Industrial Precision: Reliable Monitoring Up to 116 PSI (8.0 Bar / 800 kPa)】Safety isn’t just about numbers; it’s about accuracy you can trust. Powered by advanced automotive-grade chipsets, Grundig delivers high-precision data feedback with ±1.5 PSI sensitivity. While other systems struggle at high pressures, ours maintains rock-solid stability up to 116 PSI (8.0 Bar / 800 kPa). From Class B motorhomes to heavy-duty pickups, enjoy the peace of mind that comes from real-time tracking with zero-latency alerts.

【Command Center for Your Rig: 5.0" HD Panoramic View】Ditch the tiny, cluttered screens of traditional systems. Our massive 5.0-inch HD panoramic display acts as a flight deck for your caravan or motorhome, allowing you to monitor up to 8 tires simultaneously without squinting. With 4/6/8 wheel-mode switchable function, whether you're navigating a 4, 6, or 8-wheel setup, the crystal-clear interface provides at-a-glance situational awareness, ensuring you keep your eyes where they belong—on the road ahead. The tire pressure warning threshold is adjustable. Low-pressure warning: 180 kPa, high-pressure: 320 kPa, user-adjustable up to 800 kPa.

【40-Meter Long Range & Stable Signal】 Specifically designed for large vehicles, the system features a powerful transmission range of up to 40 meters. Enjoy consistent data syncing with zero packet loss, making it the perfect monitoring solution for long motorhomes, travel trailers, 5th wheels, and towed vehicles.

【High-End Imported Chips & Zero Latency】 Powered by advanced imported chipsets, this system delivers ultra-precise data feedback with zero latency. It monitors tire conditions in real-time with enhanced stability, allowing you to prevent unexpected blowouts and handle emergencies before they happen.

【Intelligent Automatic Start-Stop】 Featuring a built-in vibration sensor, the monitor intelligently powers on when it detects vehicle movement and enters a power-saving standby mode when idle. This fully automated system requires no manual operation, significantly extending battery life and ensuring the device is always ready when you are.

【Industrial-Grade Rugged Sensors】 The kit includes IP67 waterproof, dust-proof, and earthquake-resistant external sensors designed for extreme road conditions. While the ultra-tough casing can endure structural temperatures from -40°C to 125°C, the system provides stable 24-hour monitoring within an operating range of -20°C to 80°C using premium batteries. This ensures your sensors remain intact, leak-proof, and responsive even in the harshest environments.

【Recommended Signal Booster for Extended Lengths】For motorhomes, 5th wheels, or towing setups exceeding 9 metres (30 ft) in total length in total length, a Signal Booster is highly recommended. RV chassis and dense metal structures can naturally attenuate radio frequency (RF) signals. The signal booster is designed to amplify the signal from the rear tires, ensuring stable, uninterrupted 433.92MHz data transmission to your display monitor, preventing intermittent readings. Check the 'With signal booster' option in the dropdown menu if your rig is over 30ft to ensure zero signal dropouts during cross-country trips.

【Anti-Theft Security Design】 Equipped with custom anti-theft hex nuts and a dedicated wrench, the sensors lock securely onto your tyre valve stems. This specialized mechanical design effectively prevents casual opportunistic theft and ensures the sensors remain firmly attached even during high-speed highway driving or intense off-road vibrations.

【Built for Corrugations】Australian outback touring means thousands of kilometres of corrugated gravel. IP67-rated sensors with anti-vibration locking nuts are tested to survive sustained corrugation, bulldust and water crossings.

【Up to 1-Year Sensor Battery Life】Engineered for heavy-duty applications, our external sensors reliably monitor extreme tire pressures up to 8.0 Bar while maintaining optimal energy efficiency. Powered by easily replaceable batteries, each sensor delivers up to 12 months of continuous operational life under standard driving conditions. The system display will proactively alert you when a sensor battery runs low.

Ⅲ. Purchase Precautions

Before placing an order, please carefully confirm whether it is compatible with your model.

IMPORTANT: ADAPT ALARM SETTINGS BEFORE USE!
The factory default high-pressure alarm is set at 46 PSI (320 kPa) for standard passenger cars. Since RVs and motorhomes typically require 50 to 80 PSI(350–550 kPa), the system will trigger an immediate alert if used with default settings. Please RESET your high-pressure alarm limits according to your tire standards (Supports up to 800 kPa) BEFORE installation to ensure a quiet and safe journey.
