Owners of cars of the LADA Priora family are often faced with the need to upgrade the standard audio system. Factory solutions that were installed on the assembly line are obsolete and do not support modern multimedia functions. Installation Android radio radio becomes the optimal way to turn the interior of an old car into a high-tech space with navigation, Internet and high-quality sound.
The process of replacing the head unit (GU) on a first-generation Priora has its own technical nuances that distinguish it from installation in foreign cars. The main difficulty lies not in the connection of the wires itself, but in the correct integration of the new housing into the instrument panel. The wrong approach can lead to the appearance of crickets, malfunction of the buttons on the steering wheel, or even damage to the car's wiring.
In this article we will analyze in detail each stage: from choosing a transition frame to the final equalizer settings. You will learn how to maintain the functionality of standard controls and ensure stable operation of the system. Proper installation will allow you to enjoy modern functionality without compromising the aesthetics of your car's interior.
Selection of equipment and compatibility with the Priora panel
The first step is to select the correct form factor of the device. For Lada Priora 1, the standard seat is 2DIN, which allows you to install a screen with a diagonal of 7 to 10 inches. However, it is important to consider the depth of the case: the standard place is limited by the space behind the dashboard, where the air ducts and elements of the heating system pass.
When choosing a model, pay attention to the operating system and processor. Budget models running stripped-down versions of Android may become unstable when using navigation and music at the same time. It is recommended to choose devices with at least 2 GB of RAM and Octa Core series processors for smooth operation of the interface.
The critical element is transition frame. The standard hole in the Priora panel has a specific shape, different from the standard 2DIN rectangle. Without a high-quality frame, installation is impossible, since there will be wide gaps that will spoil the appearance of the interior.
⚠️ Attention: Avoid buying universal Chinese knife-edge frames. For the Priora, there are specially molded transition frames made of ABS plastic that perfectly follow the curves of the torpedo of a particular year of manufacture (pre-restyling or restyling).
Necessary tools and preparation for dismantling
Before starting work, it is necessary to prepare a workplace and tools. You don't need complex specialized equipment, but having a high-quality tool will speed up the process and reduce the risk of damage to the plastic elements of the interior.
First, turn off the power to the car by removing the negative terminal from the battery. This is a safety requirement since you will be working with electrical wiring under the dashboard. Any careless short circuit can damage the fuses or the comfort unit.
To dismantle the old radio and install a new one you will need:
- 🛠️ A set of screwdrivers (phillips and flat) of different lengths to access hidden screws.
- 🔧 Plastic spatulas for removing decorative overlays without scratches.
- ✂️ A stationery knife or side cutters for carefully stripping wire insulation.
- 📏 A tape measure or ruler for checking gaps when trying on a frame.
It is also recommended to prepare high-quality electrical tape and heat-shrinkable tubes. Twisting the wires “on the snot” is unacceptable - vibrations on the roads will quickly break the contact, which will lead to loss of sound or system reboots.
☑️ Preparation for installation
Removing the standard panel and removing the old GU
The process of removing the standard audio system on Priore begins with dismantling the decorative trim framing the radio and the heater control unit. This part is attached with latches around the perimeter and requires careful handling.
Carefully pry the plastic trim with a flat screwdriver or spatula at the bottom, closer to the gearbox levers. Move in a circle, sequentially snapping the latches. Do not use excessive force, as the plastic on older cars becomes brittle and can crack.
After removing the trim, you will have access to the four screws holding the metal housing of the original radio. Unscrew them with a Phillips screwdriver. Then gently pull the device towards you. Two main connectors will be connected to it at the back: power and antenna.
Disconnect the connectors by pressing the latches. If a standard antenna with an amplifier is installed, make sure that you have not damaged the thin antenna power wire, which often comes separately or as part of a bundle. Now the seat is completely ready for installation of new equipment.
When removing the plastic cover, warm it up with a hairdryer in the winter. Warm plastic becomes more elastic, which significantly reduces the risk of breaking the latches during dismantling.
Installation of the transition frame and fastening the case
Installation of the transition frame is the most critical stage that affects the appearance. The frame usually consists of two parts: an external decorative frame and an internal mounting cup (shaft) into which the radio is inserted.
First, try on the outer contour of the frame to the hole in the dashboard. It should fit tightly, without backlash. In some cases, especially on pre-restyling models, it may be necessary to carefully trim the plastic along the edges of the seat, but this is rarely required when using branded frames.
Then insert the radio into the inner glass of the frame. Secure it using the supplied metal corners and self-tapping screws. Make sure that the case sits firmly and does not wobble inside the frame. Any vibration of the body will be transmitted to the plastic and create extraneous noise.
Insert the assembled structure into the instrument panel. Check the gaps between the frame and the dashboard. They should be uniform on all sides. If the frame protrudes or is recessed too much, check the correct installation of the internal fasteners.
| Fastening element | Installation location | Type of fastener | Note |
|---|---|---|---|
| External frame | Torpedo front panel | Latches / Glue | Requires precise fitting |
| Metal shaft | Inside the seat | Standard screws | Holes from the old GU are used |
| GU brackets | Side faces of the radio | Screws 3.5mm | Fixed radio in the shaft |
| Inner rim | Between the shaft and the frame | Latch | Ensures solidity of the structure |
Electrical connection and pinout of connectors
Modern Android radios use a standard connector ISO, which greatly simplifies the connection. However, on a Priora, the standard wiring may differ in the color of the wires or have specific connectors that are not directly compatible with ISO.
In an ideal scenario, an adapter from LADA to ISO wiring is used. This allows you to connect without twisting or compromising the integrity of the standard car wiring. If there is no such adapter, you will have to connect the wires by color. Plug & Play without twisting or compromising the integrity of the car's standard wiring. If there is no such adapter, you will have to connect the wires by color.
The main lines that need to be connected:
- 🔴 Constant plus (+12V): usually a yellow wire. Responsible for storing settings and clocks. Must be connected directly to the battery through a fuse.
- 🟡 Ignition (ACC): usually red wire. Supplies power only when the key is turned. Serves to turn on the radio.
- ⚫ Ground (GND): black wire. Connects to the car body or the standard negative wire.
- 🔵 Antenna control: blue wire with a white stripe. +12V is supplied when the radio is turned on to activate the antenna amplifier.
To connect the wires, use special clamp connectors or soldering followed by heat shrink insulation. Twisting the wires and then wrapping them with electrical tape is an unreliable method that can lead to oxidation of the contact and fire.
⚠️ Attention: It is strictly forbidden to connect the constant positive and ignition wires together if you want to save the settings when the engine is turned off. If you combine them, the radio will reset the time and equalizer every time you turn off the engine.
Nuances of connecting a CAN bus
On some Priora trim levels, volume control and display of information on the radio display is carried out via the CAN bus. To do this, you will need an additional CAN adapter, which is connected to the gap in the standard wiring. Without it, the buttons on the steering wheel will not work, and the sound settings will be reset.
System setup and integration with car functions
After physical installation and first switching on, the software configuration stage begins. Android radios have a wide range of functionality that requires initial configuration for a specific vehicle.
First of all, go to the factory settings (usually a password is required, for example 1234, 8878 or 3368, check the instructions for your model). Here you need to select the type of car and the configuration of the buttons on the steering wheel. Select Lada Priora or a universal control protocol from the list.
Next, configure the screen parameters. The resolution should match the matrix of your device, and the brightness can be set to automatically adjust depending on the time of day. This is important for comfortable use of navigation at night.
Do not forget to check the operation of the parking sensors if it is connected to the radio. In the parking settings section, set the sensor sensitivity zones. When reversing, an image from the camera (if equipped) and a sound indication of obstacles should automatically appear on the screen.
Correctly setting the Factory Settings is critical for the correct operation of the buttons on the steering wheel and displaying information about the vehicle on the radio screen.
Frequent problems and ways to fix them
During operation, typical problems that Prior owners encounter after installing non-standard head units may arise. Understanding the causes allows you to quickly eliminate the malfunction.
One of the common problems is background and noise in the speakers when the engine is running. This indicates poor ground contact or interference from the generator. Check the connection point of the black ground wire - it must be stripped to metal and securely clamped with a bolt.
If the radio reboots spontaneously when the starter is started, it means that the voltage in the on-board network is dropping. In this case, it is recommended to run a separate thick power wire directly from the battery, installing a fuse in the immediate vicinity of the terminal.
Also, users often complain about the device overheating in the summer. Since the Priora does not have powerful ventilation in the center console area, make sure that there is air flow to the rear of the radio. Do not seal the ventilation holes on the device body.
Why does the radio turn off when you turn the key to the ACC position?
Most likely, the constant power and ignition wires are mixed up. Check the connection diagram: the red wire (ACC) should receive power only when the ignition is on, and the yellow wire (BAT) should receive power constantly.
How to improve the sound quality on the standard Priora acoustics?
Use the built-in DSP processor in the radio settings. Boost frequencies above 10kHz for clarity and add some bass between 60-80Hz. Also check the balance and fader settings.
Is it possible to leave the car's standard USB port?
Yes, but this will require a special adapter that integrates the standard connector into the Android radio system. Otherwise, you will have to remove a new USB cable from the glove compartment or ashtray.
What to do if the microphone for speakerphone does not work?
Check whether the external microphone included in the kit is connected. The built-in microphone in the radio often works worse due to engine noise. Place an external microphone on the windshield pillar or sun visor.
Is the radio compatible with the car's Canbus system?
Most modern models support operation via the CAN bus, but require the purchase of a separate decoder. Without it, the radio will work like a regular audio device without integration with the on-board computer.
