Lexus ES 300h Android Head Unit Review: Touchscreen Upgrade

Upgrade Your Lexus ES 300h Infotainment System

The 2019 Lexus ES 300h is a car celebrated for its luxurious interior and quiet ride. However, many owners find the factory navigation system frustrating, primarily because the original monitor doesn't support touch input. While it features Atlant V5 maps, all interaction is done via a touchpad, which can be cumbersome, especially when trying to quickly change destinations or access features while driving. This limitation is a common complaint among Lexus owners, but a smart solution is now available to enhance the infotainment experience.

Introducing the Q-ROIX Android Head Unit for Lexus ES 300h

The Q-ROIX is a dedicated Android head unit specifically designed for the Lexus ES 300h. Its key advantage is seamless integration with the factory display, preserving the car's sophisticated interior aesthetic. This retrofit allows for direct touchscreen control of the navigation and infotainment system, transforming the user experience into something akin to using a smartphone. A significant benefit is the complete retention of original functions. Pressing and holding the factory MAP button for two seconds switches the display to the Q-ROIX interface, and pressing it again reverts to the original system. This means you can effortlessly switch between the factory setup and the new Android system as needed.

Seamless Installation with Jack-by-Jack Wiring

Modifying the electronics in luxury vehicles like the Lexus ES 300h can be complex, as incorrect wiring can potentially disrupt original features. However, the installation process for the Q-ROIX utilizes a "jack-by-jack" method. This approach connects the new unit using compatible adapters without altering the factory wiring harness. This ensures the integrity of the original system and makes it easy to revert to the factory setup if desired, a crucial consideration for owners of high-value vehicles.

Enhanced Performance with Android 8.1 and HEXA Core CPU

The Q-ROIX is more than just a navigation device; it's a compact computer running Android 8.1 with a HEXA Core CPU. This configuration delivers smartphone-level app performance. By connecting to Wi-Fi, you can download and use a variety of applications such as TMAP, Kakao Map, Melon, YouTube, and Netflix directly on your car's screen. The unit comes with Atlant V5 maps pre-installed, and offline maps can be stored via a USB port located in the glove box. The primary advantage is the freedom to choose and use your preferred navigation apps.

Real-Time Traffic Updates with TMAP and Kakao Map

For Lexus ES 300h drivers who frequently navigate urban commutes or undertake long journeys, real-time traffic information is essential. While Atlant V5 is a capable navigation system, TMAP and Kakao Map offer superior real-time traffic data. The Q-ROIX allows you to use either of these apps, giving you the flexibility to choose based on current needs. In congested urban areas, traffic conditions can change rapidly, making up-to-the-minute navigation updates invaluable for saving time.

Enjoy Multimedia On-the-Go

Unlike many factory car systems that focus solely on driving assistance, the Q-ROIX offers a richer multimedia experience. You can enjoy content from YouTube, Netflix, and mobile TV services directly on your car's display. While certain features may be restricted during driving for safety, you can freely access video content when parked or during stops.

Installation Process:

1. Disconnect the vehicle's battery for safety.
2. Carefully remove the factory infotainment trim panels to access the original display connector.
3. Connect the Q-ROIX interface module using the provided "jack-by-jack" adapters, ensuring all factory connectors are securely reattached.
4. Route the necessary cables (e.g., for Wi-Fi and USB) to accessible locations like the glove box.
5. Reassemble the trim panels and reconnect the battery.
6. Power on the system and complete the initial Android setup, including Wi-Fi connection.
