It is possible to display AUX on the standard Toyota Camry 40 radio only if certain changes are made in the system.
You can do this yourself only if you have knowledge of a certain technique, and this article will discuss this issue in more detail. So, let's go.
With the car engine running, it is necessary to move the gearbox to the lowest position, after which the engine must be stopped. This must be done in order to remove and disassemble the dashboard. Further:
- The side trims are removed first;
- then the upper pad for air outlet;
- you need to disconnect the clock and emergency light connector;
- then you need to pry the panel surrounding the gear knob with your hands, remove it simply, no special effort is required;
- It is also necessary to disconnect the seat heating connector;
- then the ashtray is pulled out, if one is included in the package;
- then you need to lift the panel that remains around the gear knob. There is also a stand for glasses;
- There you need to disconnect the cigarette lighter connector;
- then the lower console comes off very simply and effortlessly, at this moment you need to disconnect the connectors leading to it, there are usually two of them;
- then you need to use a 10mm wrench, they need to unscrew the two bolts located on top of the radio, in the same place where the air outlet grille for the air conditioner and furnace was located;
- then you need to unscrew the two bolts from the bottom, under the radio.
At this stage, the dismantling of the radio with the central unit is completed.
What is this exit for?
The Aux line output in the radio is necessary to connect a smartphone, tablet or mp3 player to the player. In this case, the sound will be transmitted through the car speakers.
In some cars they are combined, and the car owner can connect the phone when answering a call. To do this, you can connect a microphone to the radio via AUX. Therefore, on the panel on top of the Aux connector it is written “AUX IN”.
In operating condition, a signal with an amplitude in the range of 0.5-1 V is supplied to the output.
There is also an amplifier that transmits sound to the speakers.
Some drivers do not know what the input in the radio with the inscription AUX means. In this case, you can mix up 2 identical connectors. Below the output with the prefix “IN”, there is a plug labeled “OUT”.
AUX OUT - a connector designed for audio output. Therefore, a wire is inserted into it to output music. Speakers are suitable for this. Unknowing motorists are faced with problems with sound output in the radio and have no idea what Aux is. Therefore, if problems arise with the volume or the player does not work, they change it, but the problem may be that the device is not connected correctly.
Screen
The ForCars CRS-300 head unit with a 9 " has a bright 2.5D IPS display. High pixel density and 1024*600 resolution made it possible to achieve very clear and detailed images. Additionally, the screen is protected with an anti-reflective and scratch-resistant coating. MultiTouch technology is convenient for navigating and viewing Internet pages. For example, scaling (moving or spreading your fingers) or rotating the image. This technology (IPS) can significantly improve color rendition and image quality on the radio screen, increases brightness and contrast. Unlike a conventional TFT screen, here the picture is clearly visible even in direct sunlight and at any angle. On an IPS panel, blacks are much more like black rather than a shade of gray. The color gamut is almost identical to natural. The viewing angle is 178 degrees.
How to use
When the Aux connector is detected on the car radio, the driver tries to determine what it is and how to use this function. The system can be found in many devices that reproduce sound. However, older cassette players or older versions of CD radios do not have a line-out. But this does not mean that a car enthusiast will not be able to connect a player or smartphone to play his music on the speakers.
To start listening to music in the car, you will need to determine how the playback device is connected via Aux and start listening to music from other sources. If the radio has an AUX plug, then to start using it you need a wire, where the jack size should be 3.5 mm. On the other side of the adapter there are several connectors for connecting an external device. If the corresponding output is not found on the player, then the car owner is able to make it himself. After connecting the playback device, you can listen to music.
How to enable AUX
If AUX was originally built into the car radio, then the system will need to unlock it. To enable Aux on the radio as a device that sends a signal to the speakers, you need to put the player in standby mode. To do this, press the SRC button, then enter the menu using MENU. You will need to hold the button until the system is activated. In the menu, scroll the right control knob to toggle Aux. The car radio display may show AUX ON/OFF, which indicates whether the input is on or off.
After the radio display says that Aux is on, press the MENU button. This will help you log out and save your settings. Then you can connect the AUX wire to the radio.
Bluetooth adapter
If for some reason it is impossible to use standard adapters, then you can purchase a Bluetooth adapter. The device connects to any 3.5 mm jack connector. In the car radio, the Bluetooth adapter is connected to the AUX input. The device wirelessly transmits an audio signal. The advantages of connecting AUX with a Bluetooth adapter include:
- Wireless signal transmission. Wires in the cabin interfere with the driver and look ugly.
- High-quality audio codec. Playback of audio tracks occurs without jamming, and a clean signal is output.
- Convenient and easy to use. The adapter is connected directly to AUX and connected to the car radio without additional actions or manipulations; To turn it on, press the button.
- Output sound from multiple devices. The adapter provides for connecting 2-3 external devices.
- Bluetooth is easy to use. You can switch music or adjust the volume using your voice or remote control; if necessary, use the buttons on the device body.
An adapter connected via AUX to a player in a car costs around 500 rubles. Minor disadvantages include the fact that the device requires recharging.
Cable
In addition to the adapter, there is a special AUX cable for the car radio, which is sold in a car equipment store. It can be found in the accessories section. Sometimes the adapter is already included in the factory configuration.
In this case, the connector should be on one side, as for 3.5 mm jack headphones, and on the other, intended for a smartphone or other external device with music. To connect the cable to the radio, you will need to connect the Aux in the menu, and then you should not confuse the 2 outputs and insert the plug into the Aux labeled “IN”.
DSP (Digital Signal Processor)
Built-in 18 or 36 band DSP (Digital Signal Processor). A specialized processor on the ADAU1701 chip is designed for processing digitized signals. Thanks to this, the sound can be adjusted and adjusted as you like:
LUD – loudness compensation. The left slider is for low frequencies, the right is for high frequencies.
PHAT - stereo extension.
HIGHT PASS - high pass filter from 60 to 120Hz.
BASS EQ – amplification of an arbitrary frequency in the low-frequency range, 60 - 100Hz.
SUB - subwoofer level.
How to make AUX
If the player in your car does not have a line input, then it is useful to know how to output music from devices. To do this, you will need to make a plug in the radio with your own hands. Car owners begin to think about how to make an AUX input if there is none, and begin to purchase the necessary tools. First you need to purchase a wire and plug. You don’t have to buy them in the store, because... The connector can be removed from old headphones. To avoid problems after connection, the wire must be taken without damage.
The jack connector in the headphones is divided into 3 parts. In this case, the largest colored wiring at the base relates to the overall sound. To solder the parts you will need to use a soldering iron. Additionally, you need to take solder and a multimeter.
CD on the radio
The disc player is equipped with an AUX input. Some manufacturers do not display it on the dashboard and do not know how to listen to music from an MP3 player. Therefore, the car owner must do this himself. To solder the Aux into the player, you will need to stock up on tools and consumables such as:
To make AUX in the radio, you will need to remove the decorative plates - to do this, you can use a knife and carefully pry them off. Then take a medium Phillips screwdriver and unscrew the 2 screws holding the grille. Once this is done, the mesh will come away and can be easily removed. The procedure helps to open access to the radio with a CD drive; You can make an AUX input using standard keys. This is necessary to remove the player from its niche.
After removing the car radio, you should examine the back wall of the case and find the white connector.
Instead of this output there will be an Aux input. After finding the connector, you should connect the USB cable and jumper from the HDD drive to it. Then you need to close the contacts. To install the jumper correctly, you will need to divide the upper part into even contacts, and the lower part into odd ones. To create an Aux input, jumper the bottom pins 11 and 13, counting from the left side.
Then a USB cable consisting of the following elements is connected to the input:
- left channel cable;
- right channel wire;
- shielding.
For the right channel, pin 5 is used, and for the left, pin 3 is used. Both wires are connected to a two-core cable and the connection is insulated with electrical tape. The cable and jumper are inserted into the connector of the player in the car. The creation procedure is completed, and AUX is removed not from the radio, but into the ashtray. A cable with a USB connector can be connected to the player or other devices. Soldering in the connector yourself makes it possible to use not only a USB cable; instead, you can use other adapters to connect external devices.
On the standard radio
Soldering an AUX adapter for a standard radio is not an easy process. In this case, the player is removed due to the fact that there is not always an input on the panel. In addition to the basic tools, to make the connector, you will need to prepare 3 insulated cables. The cross-section of each of them should be 0.5 cm, and the length should be 30 cm. Additionally, heat shrinkage will be required.
To connect Aux to the standard radio, you need to remove the decorative strips with a knife. A similar procedure is done with the panel near the gear shift lever. Then it is removed manually, after which access to 2 screws opens. To do this, use a Phillips screwdriver. Installation of AUX in standard radios is carried out by removing the device from the niche.
To avoid damaging anything, when removing the player, you must disconnect all the wires at the back.
Then you need to take a Phillips screwdriver and unscrew all the bolts that hold the car radio cover. The device can now be removed from the case. To install AUX in the standard radio, you need to find the following 3 points on the board:
- LCH. Indicates left stereo channel.
- RCH. Right stereo channel.
- GND. "Earth".
It is necessary to solder 3 wires to the designated contact points. After this, all cables are assembled and heat shrinked to ensure the structure is safe. The procedure for soldering the AUX is completed, and all that remains is to assemble the player.
All parts are installed in reverse order. The resulting three-wire wire is connected to the standard radio and brought out into the glove compartment or car interior, after which all that remains is to connect the 3.5 mm jack. A soldering iron is used for this. After completing the procedure, you can connect other devices to listen to music on the car speakers.
On a cassette player
If the car has an outdated player, and the owner wants to connect an AUX input to listen to music from an external device, then he will need to make a socket with his own hands. The set of tools is no different from other installation methods. The process begins with unscrewing the bolts holding the player in the niche. Then the player is removed and the screws are unscrewed from the car radio cover. After this, the tape mechanism of the cassette recorder becomes available.
The device is attached to special metal finish latches. Connecting the AUX input to an old radio is done either by removing the mechanism or leaving the structure in place. This depends on whether the device will interfere with getting to the volume control. Then the three-pin volume control is removed from the player. You need to solder 3 wires to it:
- general;
- for the left channel;
- for the right stereo channel.
To insulate these areas, you need to heat-shrink the wires. Then the tape recorder is assembled and installed in a niche. Now you should connect the AUX to the cassette player and output it to the glove compartment. To do this, a 3.5 mm jack is soldered. After this, it will no longer be possible to insert cassette tapes into the cassette player for listening, because... it will be used for the AUX input wire.
Problems and how to solve them
After soldering or on a standard radio, car owners have problems with sound transmission.
At the same time, they note that the volume is low, or the player does not work at all.
Plays quietly
If the sound coming through the Aux into the device is weak, this may be due to damage to the wire. To fix the problem, you need to check the connection cable. To do this, use a multimeter.
If the device does not show any problems, then you should increase the volume on the connected device.
Does not work
Car owners note that the player does not make sound. If AUX does not work, this may be due to the fact that the connector in the radio is turned off. Otherwise the wire would be connected to Aux OUT.
To solve these problems, you should go to the device menu and check whether the input is unlocked or not. Sometimes the problem occurs in the socket - to do this you will need to remove the radio and check the connection of the contacts.
