Vehicle-mounted interconnection box converts wired car entertainment to 2Air wireless format

This vehicle-mounted interconnection box provides a practical upgrade path for older wired car entertainment systems, enabling compatibility with modern wireless devices without replacing factory-installed equipment. The unit converts traditional wired audio and video connections to the 2Air wireless format, allowing smartphones, tablets, and other mobile devices to interface with existing car systems. With dimensions of 76 × 43 × 12.3mm, the compact design fits discreetly within most vehicle interiors, while the 0.75W power consumption ensures minimal impact on vehicle electrical systems. The 5V ± 0.2V voltage specification provides flexibility for power sourcing from standard USB outlets commonly available in modern vehicles.

Features and Construction

The interconnection box combines functional wireless conversion technology with practical physical design considerations for automotive environments. The conversion from wired to 2Air wireless format maintains signal integrity while providing the convenience of wireless connectivity.

Material and Build

Constructed from ABS PC plastic, the housing provides impact resistance suitable for vehicle environments where temperature fluctuations and vibration are common. This material selection ensures dimensional stability across the 76 × 43 × 12.3mm form factor while maintaining the precise tolerances required for reliable electrical connections. The plastic construction contributes to the overall light weight of the unit, making it suitable for mounting in various vehicle locations without adding significant mass.

Size and Practical Fit

Measuring 76 × 43 × 12.3mm, the interconnection box occupies minimal space within vehicle interiors. This compact dimension allows installation in discreet locations such as behind dashboard panels, within centre console compartments, or in glovebox areas. The small footprint ensures compatibility with various vehicle models and interior layouts, providing installation flexibility while maintaining accessibility for occasional maintenance or connection adjustments.

Uses and Placement

The interconnection box serves as a bridge between legacy wired car systems and modern wireless devices, expanding functionality without complete system replacement. This approach preserves existing investments in car entertainment infrastructure while adding contemporary connectivity options.

Event or Professional Use

For professional installation scenarios or vehicle customisation projects, the interconnection box provides a standardised solution for integrating wireless capabilities. The complete package including host, box, data cables, and instructions supports efficient installation workflows. The 5V ± 0.2V voltage tolerance accommodates various power supply configurations common in professional automotive environments, while the standardised 2Air wireless format ensures compatibility with a range of mobile devices used by drivers and passengers.

Everyday Home Use

For typical vehicle owners seeking to modernise their car entertainment systems, the interconnection box offers straightforward integration of wireless functionality. The low 0.75W power consumption minimises impact on vehicle electrical systems during daily use, while the compact 76mm width allows installation in convenient yet unobtrusive locations. The conversion to 2Air wireless format enables routine use with personal smartphones and tablets for music streaming, navigation audio, and hands-free calling through existing car speaker systems.

Benefits and Buying Value

The interconnection box extends the useful life of existing car entertainment systems by adding wireless connectivity capabilities that match modern user expectations. This approach avoids the expense and complexity of complete system replacement while providing contemporary functionality.

Reuse and Low Maintenance

The design prioritises reuse of existing wired car systems, preserving factory-installed components that remain functional. The low 0.75W power requirement reduces electrical load on vehicle systems, potentially extending component longevity. The ABS PC construction requires minimal maintenance beyond occasional dusting, and the standardised connections simplify troubleshooting or future upgrades should requirements change.
