Car owners Skoda Superb The second generation often face the need to expand the functionality of the regular multimedia system. Installation multifunction steering wheel It is not just a tribute to fashion, but a real increase in traffic safety, allowing you to control the audio system and phone without being distracted from the road.
The modernization process may seem difficult for a beginner, but with the right scheme and understanding of the logic of the work. CAN buses The problem of the car can be solved on its own. In this article, we will discuss in detail all the nuances of connecting control buttons on the steering wheel for models with different types of head units.
Selection of equipment and equipment compatibility
Before proceeding to disassemble the cabin, you need to accurately determine the current configuration of your Skoda Superb. Not all steering wheels and not all tapes support the control function of the media player. If you have a basic version with a simple audio system, installing buttons may require replacing your head unit with a more advanced model, such as one with navigation or support for Android Auto.
The key factor is availability CAN buses in your car. In earlier versions Superb (until 2013) control could be carried out through resistive voltage divider signals, which requires the use of special adapters. The new models already have a digital bus where the signal from the buttons is transmitted directly, simplifying the integration process.
Pay attention to the type of connector that is used to connect the buttons. Depending on the year of release, it may be a connector. 6-pol or 12-pol. An error in the selection of an adapter will lead to the system inoperability or even to a short circuit.
- π Check for a connector under the button in the steering wheel (sometimes there is a plug).
- π Make sure there is a regular wire harness with a button connector under the steering wheel.
- πΎ Determine the exact model of the head unit (RCD-300, RCD-510, RNS-510 or newer).
β οΈ Warning: An incorrectly selected adapter can cause the head unit to not see button presses or to register false commands.
Tools and materials for work
For high-quality installation, you will need a standard set of automotive tools, but there are specific positions that can not be done without. You will need to gently dismantle the steering lining without damaging the airbag and casing, so plastic clips should be in perfect condition.
The main tool will be clip remover Or a thin screwdriver with rounded edges. Also, it is necessary to have a multimeter to check the presence of voltage on the contacts and vertebrae of the chains. Without this equipment, you risk damaging the wiring or connecting the device to a circuit where it shouldnβt be.
Donβt forget about the heat pipe, and maybe the heat pipe. soldering ironif the factory insulation of the wires is not suitable for reliable connection. The quality of contact directly affects the durability of the control system.
- π Plastic removers for dismantling panels without scratches.
- π Multimeter to check voltage and circuit integrity.
- π§° A set of transition connectors and adapters of the CAN bus.
βοΈ Preparing to install the multifunction steering wheel
Dismantling and access to wiring
The first step is to shut down the battery. This is important because you will be working in the vicinity of the safety-bag. Any short circuit in the Airbag circuit can lead to its unintended operation, which is extremely dangerous.
The steering wheel should be removed. It is usually mounted on two latches on the back. Carefully tuck them in to release the fixtures. Try not to make excessive efforts to avoid breaking down plastic that becomes brittle over time. After removing the lining, you will get access to the steering column contacts.
If your model does not provide a regular space for buttons, you may need to replace the entire steering wheel with an option with an already installed control module. In this case, make sure that the new steering wheel has a compatible airbag and connectors.
How to remove the steering wheel without damage?
Remove the negative terminal of the battery, wait 10 minutes. Find technological holes on the back side, insert a thin screwdriver and gently press on the fixtures, while pulling the patch on yourself.
After examining the free space, you will see connectors for connecting additional devices. This is where yours will be connected. adapter. The wiring must be carefully stowed so as not to get under the moving parts of the steering wheel when it is rotated.
β οΈ Warning: Never connect or disable airbag connectors when ignition is on and the battery is connected.
Connecting the adapter and control buttons
Connection multifunction steering wheel It is carried out through a special adapter that converts the button signals into commands that the head unit understands. Insert the adapter connector in the standard port on the steering column, if it is provided. If there is no port, the wire will have to be connected directly to the tourniquet, observing the color marking.
For a type head unit RNS-510 or RCD-510 The adapter usually has only two wires that connect to the contacts of the CAN bus. In simpler systems, a connection to a signal wire running from the steering buttons to the comfort unit may be required. Use it. connection diagramIt comes with an adapter.
After connecting all the wires, carefully isolate the connection places. Use thermal shrinkage to eliminate vibration and contact with metal parts of the steering column. Excess wires carefully remove and fasten with screeds so that they do not interfere with the operation of the steering column.
- π Connect the adapter to the connector on the steering column.
- π΄ Connect the wires according to the color scheme from the instructions.
- π Secure and isolate all connections with thermal shrinkage.

Coding and activation of functions
Physical connectivity is only half the battle. In order for the buttons to work, you need to coding car. This is done through a diagnostic scanner with OBD-II support. Without encoding, the radio will not know that a new control module is connected to the system.
You will need to go to the media control unit (usually module 56 or 19) and change the settings. Depending on your software, you may need to enable the option βMultifunction Steering Wheelβ or change the encoding length. Incorrect settings can result in track titles or phone contacts not being displayed on the screen.
For coding often used programs such as VAG-COM (VCDS) or ODIS. In some cases, it is enough to simply reboot the tape after you connect if the system automatically recognizes new hardware, but this is rare.
If you are not confident in your abilities, it is better to contact the professionals, as a coding error can lead to malfunctions in the operation of other electronic systems of the car.
β οΈ Note: An error in coding can lead to errors in the airbag system or ABS.
Coding is a mandatory step. Without it, the buttons will be pressed, but the signals will not reach the head unit.
Compatibility table for adapters
For clarity, we give a table of compatibility of various adapters with models of head units and control types. This will help you choose the right kit before buying.
| Radio model | Control type | Required adapter | Note |
|---|---|---|---|
| RCD-300 / RCD-310 | Resistive. | Divisor adapter | Requires precise resistance adjustment |
| RCD-510 / RNS-510 | CAN bus | CAN adapter (2 wires) | Easy connection, support for menu |
| Android radio | CAN bus | Universal CAN block | Depends on the Android version |
| Basic audio system | No support | Not applicable | Replacement of the head unit is required |
Note that for basic systems without support for control of the buttons on the steering wheel, installing the multi-wheel itself is meaningless without replacing the head unit. Without replacement of the head unit, the functionality of the buttons will not be implemented even if there is an adapter.
Resolving Typical Problems and Errors
Even with the right connection, problems can arise. The most common mistake is the lack of response to pressing buttons. In this case, check for voltage on the adapter connector and make sure that the coding was done correctly.
Another problem is that the buttons only work one way (for example, only the volume, but not the switching of tracks). This may indicate an incorrect circuitry for connecting the CAN bus wires or a malfunction of the adapter itself. Try replacing the adapter with a fully functional one.
Sometimes there is a situation when the buttons work unstable when the engine is on. This may be caused by interference in the network. In this case, it is recommended to establish additional capacitor or a interference filter in the power circuit of the head unit.
- π Check the reliability of the contacts and the absence of oxidation.
- π Check the encoding through the diagnostic scanner.
- π Replace the adapter if the problem persists.
If the buttons are running late, check if you have third-party apps that conflict with the multimedia system.
