4.5. General Installation Steps

Before permanent installation, it is recommended to test the unit's functionality.

1. How to find the power cord of the car: First, turn the car key to the ACC state. Set a universal multimeter to 20V. Connect the black probe to the power ground (the outer metal casing of the cigar lighter) and use the red probe to test each wire of the car. Normally, a car has two wires around 12V (some cars only have one). These are the positive pole lines. To distinguish between ACC and memory lines: After finding the two positive pole lines, remove the car key. The memory line is the one that remains electrically charged after you unplug the key.
2. How to find the ground wire of the car (negative pole): Turn the universal multimeter to the on/off beep setting. Connect the black probe to the power ground (the outer metal casing of the cigar lighter) and use the red probe to test each wire except the two power lines. The energized one is the ground wire (negative pole). Some cars have two ground wires.
3. How to find the horn line of the car: Turn the universal multimeter to the on/off beep setting. Connect the black probe to any wire except the power cord and ground wire. Then use the red probe to test each remaining wire. The energized one is the horn wire. Use the same method to find the other horn lines.
4. How to test whether the unit works properly: When you receive the unit, it's best to test it with a battery or power supply before installation. Wiring method: Twist the red wire and yellow wire together and connect them to the positive pole. Connect the black wire to the negative pole. Then press the switch to turn on the unit and connect a horn to the horn wire. (Two wires connected to the horn are of the same color. The white wire should be connected to the positive pole and the white wire with a black part connected to the negative pole of the horn. You can make no distinction between the positive and negative poles of the horn.) Then test the function of the unit.

4.6. Reversing Camera Wiring

This section describes how to connect the reversing camera to the unit.

Connection Steps:

1. The first step is to find accessories (accessory: one camera + one power cord + one video cable).
2. The second step is to find the wiring port. First, find the reversing control line on the power line of the unit. The control line is a pink line or brown line. Connect this line to the positive pole of 12V, and the screen will turn blue. Find the CAME video input interface at the back of the unit, and find the positive and negative of the backup light.
3. The third step is to connect: there are two sockets on the camera. The red socket is connected to the power cable, the yellow is inserted into the video cable. The red wire of the power cable and the wire of the video cable are screwed together on the positive pole of the reverse lamp. The black wire of the power cable is not used. The other end of the video cable is connected to the CAME video input interface on the back of the unit. The red line coming out of the video line is connected to the reversing control line of the power line.

4.7. Physical Installation

1. Fix the bracket on the left and right sides of the machine with screws, and adjust the position of the bracket according to the actual installation.
2. Screw the machine into the mounting position of the central console of the car.

Mounting Sleeve Installation:

• Put the mounting sleeve into the dashboard.
• Bend the tabs of the mounting sleeve outward into the dashboard for a secure mounting.

Securing and Removing the Unit:

• If necessary, use a strap to secure the back of the unit in place. The strap can be bent by hand to the desired angle.
• To remove the unit, insert the release keys on both sides of the unit and then pull the unit out from the dashboard.

4.8. Navigation Antenna Installation

First, you should tighten the screws of the navigation antenna and the unit. Then, you must fix the navigation antenna module in a place that has sunlight or on the windshield. (This is very important because poor installation will affect navigation signals.)

5. Basic Functions

5.1. How to Connect Bluetooth

7. Troubleshooting

This section provides solutions to common problems you might encounter.

7.1. Unable to Boot Normally

1. If the "Yellow", "Red", "Black" wires are only connected two out of three, the unit will not start. The yellow line should be connected to the positive pole, the red line to the key control line, and the black to the negative pole. Incorrect or incomplete connection prevents booting.
2. The original car wiring and unit wiring cannot be connected by color alone, as original car wiring colors are not standard. Connecting by color may not only prevent the unit from turning on but also cause it to burn.
3. The original car plug cannot be plugged directly into the new unit, even if it fits. It cannot be used and may prevent the unit from turning on or burn it.
4. If the 3 wires are connected correctly but it does not boot: Check if the fuse on the yellow line is broken. If the fuse is fine, twist the yellow and red wires together. Turn on the key and press the unit's power button to see if it can be turned on.
5. If the fuse burns every time you change it: Do not change it again. This indicates a short circuit in the unit's protection circuit when the positive and negative poles were first connected. The unit needs repair by a professional. Do not return or replace the unit without proper diagnosis. If these steps don't resolve the issue, find a 12V battery or power supply, twist "yellow" and "red" together with the positive, and black to the negative pole. Press the button to check if it boots. If it boots, the original car wiring is incorrect or problematic. If it doesn't boot, the unit is broken. Carefully check the wiring; do not blindly suspect the unit.

7.2. Automatic Shut-down

1. Cable connection error: If the blue cable (automatic antenna power supply) is connected to the unit's power cable, an automatic shutdown will occur. Follow the correct wiring method to solve this.
2. Unstable voltage: Find a 12V-5A power supply and re-test to see if it automatically shuts down. If it doesn't shut down, replace your power supply. If it still shuts down, the problem is with the unit.

7.3. Having Noise

1. Original speaker power too low: When the unit's volume is turned up, there will be noise. Solution: When replacing the speaker or listening to music, the volume should not be too high.
2. Speaker cable grounded: Solution: Take the bare speaker cable and connect it directly to the unit's speaker cable.

7.4. Remote Control Cannot Be Used

Test method: Turn on your mobile phone's camera and point it at the remote control's IR emitter. Press a button on the remote control to see if the phone's screen lights up. If it doesn't light up, there's no power. Replace the battery. If it lights up, the remote control is working correctly.

7.5. Settings Cannot Be Saved (No Memory)

1. The yellow line and the red line are connected together (separate yellow to positive, red to key control).
2. Yellow and red wires are reversed (just change positions).

7.6. Product Smoke Indicates Internal Circuit Burn

If the product emits smoke, it indicates that the internal circuit has burned, and changing the FUSE will not solve the problem. In this case, the unit needs to be repaired.

7.7. Sound Adjustment Issues (Equalizer, Volume)

1. Adjusting sound: Please turn the volume knob to adjust.
2. Equalizer settings: Generally, press the volume knob to display "SEL" for equalizer, and rotate the volume button to adjust each sound effect.
3. Sound cannot be adjusted:
   1. Please reset the unit or unplug and replug the power cord.
   2. The volume knob is broken and needs to be replaced.

7.8. Reversing Image Not Displayed

1. Incorrect or insufficient wiring. Refer to the "Reversing Camera Wiring" section for correct connection.
2. The camera is broken. If the lamp connected to the camera does not light up when properly wired, the camera is faulty and needs replacement.

7.9. USB Flash Disk Not Playing

1. USB flash disk cannot play: Format the USB flash disk with FAT32 file system, re-download songs, and try again. If it still doesn't work, replace the USB flash drive. Check its content on a computer; if empty, download again.

7.10. FM Not Receiving Programs

1. The antenna plug is not fully inserted, the antenna is disconnected, or the line is disconnected.
2. To search for channels, hold the AMS button for 2 seconds. The unit will automatically search, or you can press the up and down buttons for manual search. If the above two points don't solve it, unplug the antenna plug and insert a screwdriver or metal strip instead of the antenna.

7.11. No Sound After Installation

The unit is tested before shipment. If there is no sound, it is usually a wiring error or the original car speaker wire is short-circuited with iron. Do not doubt the unit. Check as follows:

1. Check if the speaker cable is short-circuited and connected. Reconnect any faulty connections.
2. Check the number of speaker cables according to the original speaker cable. If there are only two speaker cables, it means the original car line does not match the unit. You need to re-route the original car line. One speaker must lead to two speaker wires; two speakers must have four speaker cables available.

7.12. No Sound After A While

Disconnect all speaker cables from the unit (do not remove all of them). Find an external speaker and connect it to the gray and purple wires of the unit's tail line. Connect any green wire, then check for sound. If there is sound, the car's speaker line is short-circuited with iron or the speaker is damaged. If there is no sound, the unit is broken.
