This document describes the MERCEDES Sprinter W907 (2018>) CANBUS services interface, wiring harness, and antenna adapter kit, identified by customer code CA-R-MER.005AE. This kit is designed to facilitate the installation of an aftermarket radio in a Mercedes Sprinter W907 model from 2018 onwards.

Function Description

The primary function of this kit is to provide the necessary interfaces and adapters to connect an aftermarket radio to the vehicle's electrical system and antenna. It includes a CANBUS services interface, a wiring harness, and an antenna adapter.

The CANBUS services interface is crucial for integrating the aftermarket radio with the vehicle's CANBUS system. The CANBUS (Controller Area Network Bus) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host computer. In modern vehicles like the Mercedes Sprinter W907, the CANBUS system manages various functions, including ignition, illumination, speed signals, and reverse signals. Without a proper CANBUS interface, an aftermarket radio might not receive these essential signals, leading to incorrect operation or a lack of functionality. This interface ensures that the aftermarket radio can correctly interpret and utilize the signals from the vehicle's CANBUS, such as parking, reverse, and speed signals, which are often required for advanced radio features like navigation, parking camera integration, or speed-sensitive volume control.

The wiring harness provides the necessary electrical connections between the aftermarket radio and the vehicle's wiring. It typically includes connectors that match the standard ISO connectors found on many aftermarket radios, as well as connectors that interface with the vehicle's existing wiring. This eliminates the need for cutting or splicing the vehicle's original wiring, preserving the integrity of the car's electrical system and simplifying the installation process. The harness is designed to carry power, ground, speaker signals, and other control signals between the radio and the vehicle.

The antenna adapter is included to ensure compatibility between the aftermarket radio's antenna input and the vehicle's antenna connector. Vehicle manufacturers often use proprietary antenna connectors, which may not directly match the standard antenna inputs on aftermarket radios. The adapter bridges this gap, allowing the aftermarket radio to receive radio signals effectively.

- 5- to CAR ANTENNA-CONNECTOR: Connects to the vehicle's existing antenna cable.

Usage Features

The kit is designed for straightforward integration of an aftermarket radio into the specified Mercedes Sprinter model.

Plug-and-Play Installation: By providing specific connectors for both the radio and car sides, the kit aims to offer a plug-and-play solution, minimizing the need for complex wiring modifications.
Retention of Vehicle Features: The CANBUS interface ensures that essential vehicle signals (parking, reverse, speed) are retained and made available to the aftermarket radio, allowing for the full functionality of features that rely on these signals.
Simplified Wiring: The pre-wired harness simplifies the installation process by consolidating multiple connections into a single, organized unit.
Antenna Compatibility: The included antenna adapter resolves potential incompatibility issues between the vehicle's antenna and the aftermarket radio.

Maintenance Features

While the kit itself does not require ongoing maintenance, the following points are important for its long-term reliability and performance:

Professional Installation Recommended: The manual explicitly states that "All installation work must be performed by a qualified professional installer only." This is crucial to ensure correct wiring, prevent damage to the vehicle's electrical system or the new radio, and guarantee proper functionality of the CANBUS interface. Incorrect installation can lead to electrical faults, component damage, or loss of vehicle functions.
No User Serviceable Parts: The components of the kit (CANBUS interface, harness, adapter) are sealed units and are not designed for user repair or modification.
Durability: The components are manufactured to withstand the typical automotive environment, including temperature fluctuations and vibrations.
Warranty and Liability: The manufacturer/dealer explicitly states that they are "not liable for any kind of incidental or indirect damages" resulting from installation. This underscores the importance of professional installation.
Technical Changes: The document notes "Technical changes possible" and "No liability for misprints," indicating that specifications may be updated, and users should refer to the latest documentation if available. The document version is dated 01/2019.

In summary, this kit provides a comprehensive solution for installing an aftermarket radio in a Mercedes Sprinter W907 (2018+), ensuring electrical compatibility, retention of key vehicle signals via the CANBUS interface, and proper antenna reception, all while simplifying the installation process for qualified professionals.
