This article documents the installation and customization of an Xtrons PA7746BP Android 7.1 head unit in a BMW E46. This comprehensive guide covers everything from the initial installation to advanced modifications, including addressing common challenges like HVAC relocation and reverse camera integration. This upgrade significantly enhances the in-car experience for E46 owners.
Choosing and Installing the E46330d Head Unit Alternative
After much deliberation, an Xtrons PA7746BP 7″ Android 7.1 head unit was chosen as an upgrade for the BMW E46. Purchased from eBay seller “Audio Visual Tech”, this unit offers a modern alternative to the factory radio. While many manufacturers offer similar Android head units, they often share common components and functionality. The installation process was straightforward, taking approximately 20 minutes. Numerous online resources and YouTube tutorials provide detailed instructions for those unfamiliar with the process.
Relocating the HVAC Controls
A common issue with installing aftermarket head units in the E46 is the need to relocate the lower climate control (HVAC) unit. While a specialized relocation bracket is often recommended, a more cost-effective solution was implemented. By positioning the HVAC unit slightly forward and securing it with a small piece of painted MDF, a secure fit was achieved without the need for the expensive bracket.
This modification resulted in a less noticeable gap at the top of the HVAC unit, maintaining a clean appearance. The gap is less conspicuous than if the unit were pushed all the way back. While not as rigid as the bracket solution, it provides sufficient stability for daily driving and operation.
Customizing the Android Interface
The Xtrons unit’s built-in features, including the equalizer (EQ), offer significant improvements over the factory system.
Beyond the factory settings, the Android platform allows for extensive customization. Utilizing the CarWebGuru launcher significantly enhances the user interface, providing a more intuitive and personalized experience.
Integrating a Reverse Camera
To further enhance functionality, an Xtrons reverse camera was installed. The camera was mounted on the number plate light plinth, requiring minimal modification.
The camera’s wiring was routed through existing openings and interior panels, connecting to the reverse lights for automatic activation when shifting into reverse.
The addition of the reverse camera significantly improves visibility and safety while maneuvering. The built-in LED lights on the camera should provide adequate illumination in low-light conditions. Overall, the Xtrons head unit provides a comprehensive upgrade to the BMW E46’s infotainment system. The improved functionality, customization options, and ease of installation make it a worthwhile investment for E46 owners seeking a modern driving experience. While this specific model may not be readily available, searching for “E46330d” or similar terms will likely yield comparable Android head unit options for the BMW E46. This guide serves as a valuable resource for anyone considering a similar upgrade.
