The process of dismantling a car multimedia system based on Android often becomes necessary when technical failures occur, the desire to upgrade the device to a more modern model, or for carrying out work on noise insulation of the interior. Unlike standard head units, Chinese Android radios have a specific housing design and mounting system, which can vary depending on the manufacturer and form factor. Incorrect removal actions can lead to breakage of the plastic latches, damage to the display, or even a short circuit in the on-board network.
Before starting any manipulations, it is critically important to turn off the power to the car. Although many craftsmen ignore this stage, relying on accuracy, the risk of accidentally shorting the connector contacts ISO to the metal body of the radio during removal remains high. This can damage not only the device itself, but also the car's fuses or power control unit. Therefore, the first step should always be to disconnect the negative terminal of the battery, which guarantees complete safety of the electrical circuit.
Next you need to prepare a working tool. There is no universal key, as manufacturers use different types of latches. You may need plastic spatulas, a set of screwdrivers (Phillips and flat-head), socket wrenches, and, in some cases, special metal pullers. Preparation of the workplace also plays a role: ensure good lighting of the interior and free up space around the center console so that nothing interferes with access to the device.
Determining the type of fastening and housing design
The first stage of successful dismantling is a visual inspection of exactly how yours is installed. car radio. There are two main ways to fix devices in a mounting location: using a metal shaft (sled) and direct installation in a plastic frame of the console. Understanding this difference determines the entire further algorithm of actions and the necessary tool.
In the case of a metal shaft, the device is held inside a steel box with special spring tongues. Typically, such systems require the use of two thin metal plates that are inserted into slots on the sides or top/bottom of the bezel. When these plates are pressed simultaneously, the internal latches are released, allowing the body to be pulled out. This is a classic scheme for many format models 1DIN i 2DIN.
โ ๏ธ Attention: Never try to pry off a metal panel with a screwdriver without using a protective gasket. The sharp edges of the tool will instantly leave deep scratches on the chrome frame or scratch the plastic of the console, which will ruin the appearance of the interior.
If your system is installed directly into a plastic niche, then the role of latches is played by the plastic latches of the frame itself or the side brackets, bolted. In such cases, preliminary dismantling of the decorative trim of the center console is often required. You can determine the type of fastening by carefully examining the perimeter of the device: the presence of small holes for keys indicates a shaft, and visible screws or the absence of obvious grooves indicate a bolted connection.
Before starting work, take a photograph of the location of all buttons and connectors on the back panel of the radio. This will help you connect the wires correctly during reinstallation or diagnostics.
Removing decorative elements and front panel
Often access to fasteners is hidden behind a decorative frame or removable front panel. On many modern Android systems the front part is monolithic with a screen, but sometimes there is a design with a removable screen or additional edging. Carefully inspect the joints between the radio panel and the car dashboard.
To remove the plastic frames, use special plastic spatulas. Metal tools are categorically not recommended here, since the plastic of consoles of modern cars is quite fragile and easily breaks under pinpoint pressure. Start prying the frame from the bottom corner, gradually moving around the perimeter. You will hear characteristic clicks - this is the plastic clips being activated.
- ๐ ๏ธ Use only specialized plastic spatulas to disassemble the interior to avoid chipping.
- ๐ Inspect the bottom of the panel: sometimes there is a hidden screw that needs to be unscrewed before removing the frame.
- ๐ Act smoothly and without jerking so as not to break the lugs of the fasteners on the back of the plastic.
If there are removable elements on the front panel, such as volume controls or decorative rings, it is also better to temporarily remove them. This will make it easier to access the main mounting screws. In some models of Chinese radios, the screen matrix itself may be glued to the body, so do not try to separate the glass from the body if this is not provided for by the design.
Removing the head unit from the seat
After all the decorative elements have been removed and access to the latches is open, the most crucial moment comes - physically removing the block. If you are using a system with keys, insert them into the appropriate slots until you hear a characteristic click. Make sure the keys are inserted deep enough to unlock the tabs.
Pull the device evenly towards you. If the radio does not budge, do not use excessive force. Perhaps one of the latches has not come off, or the side brackets are in the way. Try rocking your body slightly up and down while stretching it. In cases with bolted fastening, first unscrew all visible screws holding the housing in the shaft or console.
| Type of fastening | Required tools | Extraction features |
|---|---|---|
| Metal shaft | Two metal keys | Requires simultaneous pressing of the keys inward |
| Side brackets | Phillips screwdriver, socket wrench | It is necessary to unscrew 4 screws along corners |
| Plastic clips | Plastic spatula | Removing the entire console frame before removal |
| Combined | Tool set | First screws, then pulling by the slide |
When the body begins to come out of the niche, support it with your other hand. Do not release the device abruptly, as it is still connected by wires to the vehicle's on-board network. A sharp drop or jerk can damage the connectors on the back board.
The main difficulty when removing is access to the rear connectors, so pull out the radio just enough to comfortably work with the wires, but do not pull it out completely at once.
Disconnecting the electrical connectors and antenna
On the rear panel Android radios there is a whole set of connectors. The main one is a large white or black power connector ISO, which combines circuits for constant power supply, ignition, amplifier control and speaker outputs. There is also a separate connector for the antenna, usually round in shape, and additional interfaces for connecting cameras, microphones and USB extension cables.
To disconnect the main connector, find the latch on the connector body. Press it and smoothly pull the connector towards you. Under no circumstances pull on the wires themselves - this will cause them to tear off the contact group inside the plug. If the connector is very tight, you may want to wiggle it slightly from side to side, breaking the vacuum seal.
โ ๏ธ Warning: Before disconnecting the antenna cable, make sure you do not damage the thin center contact inside the connector. A bent antenna pin will result in poor radio reception even after reinstallation.
Additional cables, such as USB, AUX or the rear view camera wires (usually the yellow tulip), can be connected directly into the board or through separate adapters. Make a note or take a photo of where exactly each wire is inserted. In some configurations, there is a separate power supply, where the power wire goes separately from the main harness - be careful when disconnecting them.
โ๏ธ Correct disconnection of wires
Features of working with adapter frames and CAN bus
When installing non-standard Android devices adapter frames and special modules are often used to preserve the functionality of standard controls (buttons on the steering wheel) and information on the on-board computer display. These modules are connected via a connector CAN-bus or a separate wire K-Line.
If your system has such a decoder (black box with the inscription CanBus or similar), it must be disabled last. Often this block is hidden deeper in the bowels of the console or glued with double-sided tape to the metal body of the radio. When dismantling, it is important not to break the thin signal wires running from this module to the power connector.
In some cars, the standard radio is part of the climate control system or displays the car settings. In such cases, a simple replacement Android head unit without saving the corresponding control unit can lead to loss of control over the heater or window regulators. When removing, make sure that you have not accidentally disconnected other important cables running past the radio.
What to do if the wires are mixed up?
If you see that the wires are connected in the wrong color or through twists, be sure to mark them with electrical tape or stickers before final disconnection. This will save hours of work when searching for contacts in the future.
Frequent mistakes and precautions
One โโof the most common mistakes is trying to remove the radio without disconnecting the battery. Even a brief touch of the bare power wire +12V on the metal body of the car or other contact can cause sparking and burning of the fuse ACC or the main fuse of the radio. Always follow safety precautions.
Another common problem is damage to the connectors when connecting them back. The connector ISO has keys that prevent it from being inserted incorrectly, but with severe wear or makeshift repairs, this restriction may not work. Carefully check the shape of the connector before connecting. If you feel strong resistance, do not press with force - check the orientation.
- ๐ฅ Do not leave bare wires hanging in the niche - insulate them with electrical tape to avoid short circuits.
- ๐ธ Take photos at each stage of disassembly, especially the location of the bolts and the route of wiring.
- ๐งฉ Store all removed screws and plastic plugs in a separate container so that they do not get lost in the cabin.
It is also worth considering that some models Android radio have passive cooling through a radiator on the rear wall. When installing it back, make sure that the radiator does not rest against metal elements of the body, which could cause a short circuit to the device body. Use insulating tape or heat shrink to protect the back of the case.
โ ๏ธ Attention: The design of cars and radio models is constantly being updated. If you are faced with a non-standard fastening that is not in the instructions, it is better to find official documentation for your specific car model or contact a specialist so as not to break expensive interior elements.
FAQ: Frequently asked questions
Do I need to reset the radio settings before removing it?
Reset settings is not a mandatory procedure for physically dismantling the device. However, if you plan to sell the radio or transfer it to another person, it is recommended to perform a factory reset through the menu Settings โ Factory datato delete your accounts, Bluetooth pairs and saved tracks.
Is it possible to remove the radio without turning it off battery?
Technically this is possible if you act with extreme caution and avoid shorting the contacts. However, the risk of damage to the car's electronics or the radio itself is very high. Professionals strongly recommend de-energizing the network by removing the negative terminal before starting any wiring work.
What to do if, after installation, the new radio does not turn on?
First of all, check the fuses both on the radio itself (often located on the wiring harness or at the back of the case) and in the car's fuse box. Also make sure that the constant power wire (BAT+) and the ignition wire (ACC) are connected correctly and have contact.
How to remove the radio if the keys are lost?
If the keys to the mine are lost, you can try to make their analogues from thin metal plates (for example, from a hacksaw blade or old windshield wipers). Also, as a last resort, you can carefully pry the case with a thin screwdriver through the gaps, but this increases the risk of damage to the front panel.
Does removing the radio affect the car's warranty?
The very fact of removing the radio does not void the warranty for the entire car. However, if during the dismantling process the wires were damaged, the console mounts were broken, or a short circuit occurred that resulted in the failure of other electronic units, the dealer may refuse warranty repairs for these specific components.
