Owners ŠKODA Octavia A7 (including restyled version FL) are often faced with the need to expand the functionality of a standard multimedia system. One of the most effective ways is to install splitter, which allows you to connect additional devices (cameras, parking sensors, Android Auto, CarPlay) via factory connectors. But how to choose the right model among dozens of offers on the market? What connection nuances are important to consider so as not to burn the control unit or lose the warranty?
In this article we will look at all types of splitters for Octavia A7 (2013–2020), from simple rear view camera adapters to advanced multiplexers with support MIB2/MIB3. You will learn how to avoid common installation mistakes, what ŠKODA proprietary connectors must not be short-circuited, and how to configure the system so that it works stably for years. And also - compare prices, consider alternatives (for example, MirrorLink) and answer the questions that are most often asked on the forums.
Types of splitters for ŠKODA Octavia A7: which one to choose?
Splitters for Octavia A7 are divided into three main categories, each of which solves its own problems. The choice depends on what devices you plan to connect and how deeply you are ready to interfere with the standard electronics.
1. Simple video splitters (for example, for a rear view camera) - the most budget-friendly and easiest to install. They connect to the connector RCA or FAKRA on the back panel of the radio and allow you to switch between the standard image and the signal from the camera. Suitable for vehicles with MIB1 (dorestayl) and MIB2 (restyle). The main disadvantage is the lack of support for additional functions (for example, parking sensors or Android Auto).
2. Multiplexers (multisplitters) — advanced devices that are integrated into the vehicle’s CAN bus. They allow you to connect several sources at once (camera + parking sensors + smartphone), and also emulate standard signals for correct operation ParkPilot or Lane Assist. Popular models: NaviPlus, Dension, Connects2. Requires configuration via software (for example, VCDS).
3. Adapters for smartphones (for example, Wireless CarPlay or Android Auto) - not exactly splitters, but are often installed together with them. Allows you to display your phone screen on a standard display wirelessly. Important: for Octavia A7 FL with MIB3 (2018+) requires adapters that support USB-C.
- 🔧 For rear view camera: a simple splitter with a connector will do
FAKRA(price from 1,500 rubles). - 📱 For Android Auto/CarPlay: need a multiplexer with support
USBorWi-Fi(from 8,000 rubles). - 🚗 For parking sensors: only multiplexer with CAN integration (from 12,000 rubles).
- ⚠️ For MIB3: check compatibility - some splitters only work with MIB2!
- Simple for camera
- Multiplexer for multiple devices
- Adapter for Android Auto/CarPlay

Splitter connection diagram: step-by-step instructions
Installing a splitter on Octavia A7 requires caution - mistakes can lead to malfunctions MAXIDOT or even to failure of the unit Infotainment. Below is a universal diagram for most splitter models, but Before starting work, be sure to check the documentation for your device!
Step 1. Removing the radio
Remove the decorative panel around the screen (you will need a plastic spatula). Unscrew the 4 bolts in the corners (wrench TORX T20) and carefully pull out the radio. Disconnect all connectors after photographing their location.
Step 2. Connecting the splitter
The splitter is installed between the standard connector of the radio and the control unit. Main connectors:
Quadlock(main power connector and CAN bus) - Don't mix up the polarity!FAKRA(for rear view camera) - usually gray or green.USB(for smartphones) - connects to the port on the rear panel of the radio.
Step 3. Setup via VCDS
After installing the splitter, you may need to activate new functions through a diagnostic scanner (for example, VCDS or OBDeleven). For example, to enable display of the rear view camera when moving forward, you need to change the parameter in the block 5F (Information Electr.) → Adaptation → Car_Function_List_BAP → 360_camera_0x24 to the value activated.

Compatibility of splitters with MIB versions (MIB1, MIB2, MIB3)
One of the key points when choosing a splitter is the version of your multimedia system Octavia A7. You can recognize it by the VIN code or visually:
- MIB1 (2013–2016): screen resolution
800×480, no touch controls. - MIB2 (2017–2019): screen
1280×640, touch, support MirrorLink. - MIB3 (2018–2020): screen
1920×720, wireless CarPlay, voice control.
| MIB version | Suitable splitters | Connection features | Price (from) |
|---|---|---|---|
| MIB1 | NaviPlus NP-300, Dension GW550 | Requires Android Auto firmware | 6 000 ₽ |
| MIB2 | Connects2 CTSSK004, NaviPlus NP-500 | Wireless CarPlay support (optional module) | 10 000 ₽ |
| MIB3 | NaviPlus NP-700, Dension GW600 | CAN integration is required | 15 000 ₽ |
Important: splitters for MIB1 are incompatible with MIB3 due to different CAN bus protocols! If you make a mistake with your choice, the device will either not work or will damage the unit Infotainment.
⚠️ Attention: When connecting the splitter to MIB3 be sure to update the radio firmware to the latest version via ŠKODA Portal. In older versions of the software, conflicts with the CAN bus are possible, leading to an error 01308 — Central Electronics Control Module.
Common installation mistakes and how to avoid them
Even experienced car owners make mistakes when installing splitters. Here are the most common ones and how to prevent them:
1. Incorrect Quadlock connection
Connector Quadlock has 12 contacts, and if mixed up CAN-H with CAN-L, the radio will stop turning on. Always check the wiring diagram for your splitter! For example, in Octavia A7 FL contact CAN-H - this is pin 6, and CAN-L — pin 14.
2. Ignoring settings via VCDS
Many splitters require activation of additional functions in the block 5F. Without this, the rear view camera may not turn on automatically, and Android Auto will be displayed with artifacts. Use diagnostic cable and software VCDS or OBDeleven.
3. Poor contact in FAKRA connectors
If the image from the rear view camera disappears due to vibration, the problem is in oxidized contacts. Clean them with alcohol and use a contact lubricant (such as Liqui Moly Kontakt-Spray).
⚠️ Attention: Never connect a splitter to a connectorLIN-Bus(usually the yellow wire inQuadlock) - this can damage the door control unit!
What should I do if, after installing the splitter, the radio does not turn on?
1. Check the fuse S157 (10A) in the fuse block under the hood.
2. Disconnect the splitter and connect the radio directly - if it works, the problem is in the splitter.
3. Check the voltage at pin 1 and pin 2 connector Quadlock (must be 12V).
4. If the radio still does not work, reset it via VCDS (command Basic Settings → Reset).
Setting up the splitter after installation
Successful installation is only half the battle. For the splitter to work correctly, it needs to be configured. The process depends on the device model, but there are universal recommendations:
1. Rear view camera calibration
If the marking lines on the screen do not match the actual position of the car, go to the camera menu (Settings → Camera → Calibration) and adjust the parameters Height and Tilt angle. For Octavia A7 optimal values: height - 60 cm, angle - 15°.
2. Activate Android Auto/CarPlay
For wireless connection:
- Turn on
Wi-FiandBluetoothon a smartphone. - Go to the radio menu:
Settings → Phone → Wireless CarPlay. - Confirm pairing on your phone.
If the connection is interrupted, update the splitter firmware through the manufacturer's official website.
3. Setting up parking sensors
If the splitter supports connecting parking sensors, check their sensitivity in the menu Settings → Parking assistance. For Octavia A7 recommended values:
- Front sensors:
1.2 m - Rear sensors:
0.8 m
If after installing the splitter the buttons on the steering wheel stop working, reset the unit settings 16 (Steering Wheel) through VCDS. To do this, select Basic Settings → 04 and perform a reset.
Alternatives to splitters: MirrorLink, Wireless CarPlay, OBD adapters
