Many Volkswagen owners with older infotainment systems, like the RNS 510, experience limited Bluetooth functionality. Often, the ‘phone’ button simply mutes the audio, and Bluetooth is restricted to basic headset functionality. If you’re looking to unlock the full potential of Bluetooth in your VW, upgrading your Bluetooth module can be a straightforward solution.
Understanding Your VW Bluetooth Module
Initial VW Bluetooth modules, such as the “5P0 862 335 B”, often provide very basic connectivity. While they might allow your phone to act as a wireless headset, features like phone menu access and full Bluetooth control are missing. This limitation can be frustrating for drivers wanting seamless smartphone integration in their vehicles.
The Upgrade Solution: VW Premium Bluetooth Module
A popular and effective upgrade is installing a VW Premium Bluetooth interface module. The “3C8 035 730 B” module is a well-regarded option known for its plug-and-play installation. Switching to this module can instantly unlock the PHONE and BLUETOOTH menus on your RNS 510 unit, providing full control and enhanced features for devices like an iPhone 6. This upgrade allows for a significantly improved user experience with your in-car Bluetooth system.

Based on user experiences, several VW Bluetooth modules are known to offer full functionality:
- 5N0-035-730-D (2010)
- 3C8-035-730-B (2011)
- 3C8-035-730-C (2012)
- 3C8-035-730-D (2013) with Wifi support
- 3C8-035-730-E (2014) with Wifi Support
While there’s no strict requirement to match the module year to your car’s year, anecdotal evidence suggests aligning the module with a similar model year to your head unit can yield optimal results. For instance, pairing a module from around 2011 with an RNS 510 unit has proven successful for many users.
WiFi Compatibility Considerations
It’s worth noting that WiFi compatibility in some newer modules (like 3C8-035-730-D and E) is primarily designed for newer media centers found in platforms like the Mk7 Golf, which offer internet access features. Older VW units, such as those paired with the RNS 510, are not equipped to utilize this WiFi functionality.
Conclusion
Upgrading your VW Bluetooth module is a worthwhile investment for enhanced connectivity. By replacing older, limited modules with newer, premium versions like the 3C8 035 730 B, you can unlock full Bluetooth functionality, phone menu access, and a more integrated smartphone experience in your Volkswagen. Always verify compatibility and consider consulting resources like the Volkswagen compatibility checker and Ross-Tech Wiki for informed decision-making.
