BMW 4 Series Touch Navigation Upgrade Review

Why Your BMW 4 Series Needs a Touch Navigation Upgrade

The BMW 4 Series, while sharing a similar interior layout with the 3 Series, suffers from a key limitation: its stock navigation system lacks touch functionality. This makes inputting destinations or changing routes cumbersome, and the limited detail for speed camera alerts can be distracting. Consequently, many BMW 4 Series owners in areas like Gimhae and Yangsan are opting for aftermarket touch navigation systems to enhance their driving experience. This review examines the transformation of a BMW 428i after installing the Atlantech JY Z2 model.

Limitations of Stock Navigation and the Atlantech Solution

The original BMW 4 Series navigation system features a small screen with restricted information, making it difficult to grasp road conditions at a glance. The absence of touch control necessitates multiple steps for operation, leading to frustration, especially on unfamiliar routes. Speed camera warnings are also basic, often lacking crucial details that could aid safe driving.

The Atlantech Touch Navigation Installation Process

The Atlantech JY Z2 system was installed on an 8.8-inch display using a dedicated touch panel overlay. A key aspect of this installation is the ability to seamlessly switch between the original BMW interface and the new Atlantech navigation. This is achieved through a dedicated interface module that ensures full compatibility with the existing system.

Installation process:

1. The original navigation unit is carefully removed.
2. A custom 8.8-inch touch panel is affixed to the display.
3. A set-top box and interface module are connected to enable mode switching.
4. The system is configured for seamless transition between stock and Atlantech modes.

This setup ensures that all functions within the Atlantech navigation mode are fully touch-operable, while retaining the original system's feel.

Switching Between Modes

Transitioning between the stock BMW interface and the Atlantech navigation is as simple as pressing and holding the iDrive menu button. While the stock mode remains non-touch, activating the Atlantech mode unlocks full touch control for all its features. This hybrid approach offers the best of both worlds: the familiar BMW aesthetic combined with modern touchscreen convenience.

Atlantech Navigation Features in Action

Beyond its core navigation, the installed Atlantech system supports smartphone mirroring for both Android and iOS devices. This allows users to display and operate apps like Naver Maps or Kakao Map directly on the car's screen. Furthermore, installing APK files opens up possibilities for various multimedia applications.

Crucially, the accuracy of speed camera alerts is significantly improved. Unlike the stock system, Atlantech provides precise distance warnings, enhancing safety. The turn-by-turn navigation is also more intuitive, greatly reducing driving stress on new roads.

Rear Camera Integration and Compatibility

The factory-installed rear-view camera functions automatically in both modes when reverse gear is engaged, ensuring no loss of convenience during parking. The system integrates flawlessly with the original BMW setup.

Pricing and Installation Time

The cost for the Atlantech touch navigation upgrade typically ranges from ₩1,500,000 to ₩2,000,000 for the 8.8-inch system, with potential additional costs for features like backup camera integration or smartphone mirroring modules. The installation process usually takes between 4 to 6 hours.
