For Volkswagen owners with the venerable Rns-510 navigation system, the desire for modern smartphone integration, particularly wireless Apple CarPlay, is a common one. While the RNS-510 was a cutting-edge piece of technology in its time, it lacks the seamless connectivity that drivers now expect. Upgrading to a completely new head unit can be costly and complex, often sacrificing factory features and aesthetics. Fortunately, innovative solutions are emerging that allow you to breathe new life into your RNS-510, bringing wireless CarPlay and more to your existing system.
This article delves into a clever aftermarket solution that integrates seamlessly with your RNS-510, providing a factory-like wireless CarPlay experience without replacing your entire head unit. We’ll explore the benefits, installation, and user experience of this upgrade, focusing on how it can transform your older VW into a modern, connected car, all while keeping the original RNS-510 system at its core.
The Challenge of Modernizing the RNS-510
The Volkswagen RNS-510, found in models like the Eos and many others from the late 2000s and early 2010s, is a robust and feature-rich system for its era. However, it was designed before smartphone integration became a standard expectation in vehicles. Drivers looking for CarPlay or Android Auto on their RNS-510 face several hurdles:
- Expensive OEM Upgrades: While newer VW systems like MIB2 offer CarPlay, retrofitting these into older vehicles is often prohibitively expensive and complex.
- Limited Third-Party Options: Many aftermarket head units replace the RNS-510 entirely, potentially losing features like the Dynaudio amplifier integration or factory reverse camera functionality. Cheaper, generic solutions may also lack the polish and seamless integration expected in a Volkswagen.
- Desire for Wireless Connectivity: In today’s world, wireless CarPlay is highly sought after. Fumbling with cables every time you enter the car is a step backward for many drivers. While wired-to-wireless adapters exist, they can be clunky and less reliable than integrated solutions.
Enter the Kremersino/Integrated Automotive CarPlay Solution
Companies like Kremersino and Integrated Automotive have developed an ingenious solution to overcome these challenges. They offer a discreet module that hides behind your car’s Climatronic control panel and interfaces with your existing RNS-510 unit. This system utilizes an internal interface board that’s installed within the RNS-510 itself. When you want to use CarPlay, this module “hijacks” the RNS-510 screen, displaying the CarPlay interface. When you’re done, it seamlessly reverts back to the standard RNS-510 functions.
This approach offers several key advantages:
- Wireless CarPlay: Enjoy the convenience of wireless CarPlay without the need for dongles or cables.
- OEM Integration: Retain your factory RNS-510 system, including features like Dynaudio compatibility, reverse camera integration, and steering wheel controls.
- Discreet Installation: The module is hidden from view, maintaining a clean, factory look.
- Relatively Simple Installation: The system is designed for plug-and-play installation with minimal disassembly, making it a DIY-friendly upgrade for many car owners.
Installation and Setup
While a detailed step-by-step installation guide is best visualized, a helpful YouTube video (like the one from the original article) is an invaluable resource. The installation process generally involves:
- Removing the RNS-510 unit: This typically involves using radio removal keys to safely slide the unit out of the dashboard.
- Installing the Interface Board: A small circuit board needs to be carefully inserted inside the RNS-510. This is usually a straightforward process of plugging it into existing connectors.
- Connecting the CarPlay Module: The external CarPlay module is then connected to the interface board and can be tucked away behind the Climatronic panel, which provides ample space.
- Reassembly: The RNS-510 and Climatronic panel are then reinstalled.
The installation is designed to be non-destructive, meaning no wires need to be cut or spliced, preserving the integrity of your car’s original wiring. It’s essentially a plug-and-play upgrade that can be completed in under an hour by someone with basic car audio DIY experience.
User Experience and Functionality
Once installed, the CarPlay system is surprisingly user-friendly and responsive. It boots up quickly along with the RNS-510. To access CarPlay, you simply switch the RNS-510 to the AUX input for audio and then activate the CarPlay interface by either holding the “Menu” button (or “Back” button on newer controls) or by touching and holding the touchscreen.
Key features and functionalities include:
- Seamless Switching: Transitioning between the RNS-510 interface and CarPlay is quick and easy.
- OEM Microphone Integration: The system utilizes your car’s factory microphone for Siri commands and phone calls, ensuring clear audio quality. A backup microphone is also included in the kit if needed.
- Steering Wheel Control Integration: You can use your steering wheel controls for basic CarPlay navigation and Siri activation.
- Reverse Camera Retention: Your factory reverse camera continues to function as normal, seamlessly switching back to the RNS-510 display when activated. The system also supports aftermarket front and rear camera additions.
- Sound Quality: Audio is routed through the RNS-510’s AUX input, ensuring compatibility with both standard and premium sound systems like Dynaudio. Sound quality remains excellent, leveraging the existing car audio components.
Minor Considerations
While this CarPlay upgrade is a significant improvement, there are a couple of minor points to consider:
- Resistive Touchscreen Limitations: The RNS-510 uses a resistive touchscreen, which requires a firmer touch compared to modern capacitive screens. While responsive, swiping gestures in CarPlay might feel slightly less fluid than on newer systems.
- AUX Input Usage: Since the system uses the AUX input for audio, your factory AUX input will be occupied. However, with wireless CarPlay functionality, this is unlikely to be a major drawback for most users.
- Steering Wheel Button Conflicts: In some cases, there might be minor conflicts with steering wheel button assignments, such as the menu button potentially cycling through both CarPlay and the Multi-Function Display (MFD) simultaneously. However, manufacturers are often working to refine these integrations through firmware updates.
Conclusion: A Smart Upgrade for Your RNS-510
For Volkswagen owners who want to modernize their RNS-510 system without the expense and hassle of a complete head unit replacement, this wireless CarPlay upgrade offers a compelling solution. It provides a near-factory integrated experience, retaining OEM features while adding the convenience of wireless smartphone connectivity. Priced competitively compared to full head unit replacements, it represents excellent value for those looking to bring their older VW into the modern age of in-car technology. If you’re seeking a seamless and effective way to add wireless CarPlay to your RNS-510, this upgrade is definitely worth considering.
