Mercedes-Benz C-Class W205 — Android Display and Touch Controller Installation Reference

This source covers the Android display installation and replacement of the center-console touch controller. The Chinese term translated previously as “mouse” refers to the vehicle's touch controller. The product illustration shows that controller assembly, rather than a separate computer mouse or a complete display kit.

The source illustration identifies 2015–2021 Mercedes-Benz C-Class W205 vehicles. This is the source's stated scope; the exact vehicle year, original infotainment system, audio equipment, left- or right-hand drive layout, and kit version still need compatibility confirmation.

1. Product illustration

Item 01 is the Android display touch controller, with its surrounding frame. The illustration is a component reference, not a complete packing list.

2. Installation video and step navigation

The video runs approximately 6 minutes 50 seconds. The following navigation describes the demonstrated installation. Connector colors and locations refer to the filmed arrangement; they are not a universal wiring diagram. The current English video still needs correction of its opening transcript, terminology, and Chinese instructional text. Use the notes below to identify the relevant action, and obtain the missing kit instructions before working on uncertain connections or modifying trim.

1. 00:00–01:00 — Dashboard disassembly. The opening shows access around the original display and dashboard trim. At 00:20, a fastener is shown inside the center dashboard speaker recess. The current English transcript repeats “center control screen, mouse” and does not reliably describe this disassembly. The full fastener sequence, tool sizes, and trim-release procedure must be confirmed from the original footage and vehicle instructions.

2. 01:00–01:42 — Head-unit harness connection. The demonstrator identifies several connectors that are unused in the shown installation, wraps them, and connects the large adapter to the original head-unit connection. A lead is routed along the side of the dashboard. The source does not provide terminal numbers, a power/protection diagram, or a compatibility rule for treating those connectors as unused on another vehicle.

3. 01:42–01:58 — Microphone lead. The microphone connection is demonstrated and its lead is routed upward toward the headliner. The microphone mounting position and complete route are not specified. Clearance from vehicle safety equipment and moving trim must be checked against the vehicle and kit instructions.

4. 01:58–02:17 — Display leads and audio connection. The video groups the USB-related connection, additional speaker connection, and audio adapter while routing the leads toward the display. Their exact connector identities and required kit configuration are not fully documented. Do not infer pin assignments from connector color or the transcript's references to “this plug.”

5. 02:17–02:37 — Display bracket and additional speaker. The demonstrator fits the bracket using the two original display screws and shows positioning the additional speaker with adhesive. The footage does not establish screw torque, approved adhesive, or a mounting location suitable for every configuration.

6. 02:37–02:56 — Lead routing to the center-console storage compartment. The demonstrated compartment is between the front seats, not the passenger glove compartment. The video describes making an opening at the shown location to route a lead and connect the USB box. The current English “glovebox” wording is misleading. The source does not give the opening size, precise location, edge protection, or an approved modification procedure; obtain those details before making an opening.

7. 02:56–03:33 — Remove the original touch controller. With the console assembly accessible, the demonstrator releases screws, connectors, and the clipped antenna component, then releases the controller retainers and lifts the controller out. Keep track of the original hardware and connector locations. The source does not supply a complete vehicle-specific console removal procedure.

8. 03:33–04:06 — Transfer the side controls. The side button assemblies are released from their screws and clips and transferred to the replacement touch controller. The video demonstrates both sides. Keep the left and right assemblies in their original positions rather than treating them as interchangeable.

9. 04:06–04:45 — Refit the controller assembly. The replacement is seated, the original screws and connectors are refitted, and the antenna component is clipped back into place. An unused connector is wrapped in the demonstrated configuration. Whether a lead should remain unused must be confirmed for the actual kit and vehicle.

10. 04:45–05:36 — Demonstrated audio input setup. The demonstrator connects the USB box to the original USB 1 connection in the filmed storage-compartment arrangement and opens the factory media input. At 05:15, the screen shows “Media Interface 1,” “Media Interface 2,” and USB AUX. The transcript's “USB2X” is not a verified menu name. The source does not identify every supported USB box or prove audio operation on all original infotainment systems.

11. 05:36–06:43 — Linked instrument-display demonstration. The later section demonstrates an instrument display alongside the Android screen. The required additional equipment, described ambiguously in the transcript as “EBO,” is not fully identified. The demonstrator uses the steering-wheel Back control, selects the Navigation icon, and demonstrates display settings. At 06:30, the visible option is Full Screen Mode, rather than merely “the option starting with F.” This demonstration does not establish that the touch controller alone enables instrument-display integration, every navigation feature, or full-screen mode on all W205 vehicles.

3. Demonstrated results and remaining checks

The video shows the installed display, media-input selection, touch-controller work, and a linked instrument-display demonstration. The ending is branding, not a complete installation acceptance test. The archived “installation results” section contains no separate result material.

Before accepting the installation, obtain evidence for the actual kit and vehicle covering controller/button operation, audio, microphone, original vehicle functions, secure mounting and routing, and any additional instrument-display integration. No completed technical acceptance is claimed here.

4. Troubleshooting and source limits

The archived troubleshooting section contains no diagnostic steps. It therefore does not support a fault table, coding values, connector pinout, or a claim that installation requires no programming. Confirm the exact infotainment/audio configuration, adapter and USB box, wiring diagram, and any extra instrument-display hardware with the kit's documented instructions before diagnosing or changing connections.

This reference retains the existing product illustration and the video linked to this source. It does not substitute material from a different model, screen system, or controller version.
