Installation Steps
Figure 8: Installation steps using a multimeter to identify car wiring.
- How to find the power cord of the car?
First, turn the car key to the ACC state. Then set a multimeter to 20V. Connect the black probe to the power ground (the outer ironclad of the cigar lighter) and use the red probe to test each wire of the car. Normally, a car has two 12V wires (some cars only have one). These are the positive pole lines. To distinguish ACC and memory lines: Pull out the car key after finding the two positive pole lines. The memory line is the one that remains electrically charged after you unplug the key. - How to find the ground wire of the car (negative pole)?
Set the multimeter to the on/off beep gear. Then connect the black probe to the power ground (the outer ironclad 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. - How to find the horn line of the car?
Set the multimeter to the on/off beep gear. 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. Then use the same method to find out the other horn lines. - How to test whether the unit works properly?
When you receive the unit, it is recommended to test it with a battery or power supply before installation. Wiring connection method: Twist the red wire and yellow wire together and then 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 is supposed to be connected to the positive pole and the white one with 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. - How to fix the unit?
Since each car has a different way of fixing the unit and the location of the screws are different, there is no defined way to fix the unit. You may consult the fixing method of the original unit. If it was fixed by tightening screws with a steel angle, you can unload the steel angle of the original unit to both sides of our unit, then use electrician's tape to tighten the steel angle (since screw hole size is probably unmatched). If the original unit was fixed with an iron frame, you can fix the iron frame of our unit in the car first, and then push the unit to fasten it. If the size is not fit, you can wrap the unit with electrician's tape to increase the volume of the unit, and then put it in and fasten it. Or you can find a better way to fix it, but anyway, you can fix it. - How to install the navigation antenna?
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. (That's very important because poor installation will affect navigation signals.)
Reversing Camera Wiring and Fixed Machine Installation
Figure 9: Schematic Diagram of Reversing Camera Wiring and Fixed Machine Installation
- Reversing Camera Wiring: Red wire connects to the positive pole of the reverse lamp. Black wire connects to the power negative pole. Connect to CAM IN. The red/pink line from the unit attaches to the tail line of the machine (BACK - reversing detection line).
- Fixed Machine Installation:
- 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.
- Screw the machine into the mounting position of the central console of the car.
- Put the mounting sleeve into the dashboard. Bend the tabs of the mounting sleeve outward into the dashboard for a secure mounting.
- If necessary, use the 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.

- MODE(SRC): Switch function mode.
- BT(B): Enter the Bluetooth connection interface.
- RADIO: Enter the radio interface.
Connecting Bluetooth
- Turn on the unit and initiate the Bluetooth function on your phone.
- Search for the unit's user name on your phone.
- Click the connect button; your phone will show it is connected.
- To play music via Bluetooth, press the function transition button to switch to Bluetooth mode, then select songs on your phone.
- You can also dial numbers on your phone to make a phone call via Bluetooth.
5. Troubleshooting
1. Unable to boot normally
- If only 2 of the "Yellow", "Red", "Black" lines are connected, 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 line to the negative pole. Incorrect or insufficient connection prevents booting.
- The original car line and unit wiring cannot be connected by color alone, as car line colors are not standard. Connecting by color may not only prevent it from turning on but also burn it.
- The original car plug cannot be directly plugged into the new unit, even if it fits. It cannot be used, otherwise it won't turn on or may burn.
- 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.
- 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. If these steps don't resolve the issue, find a 12V battery or power supply, twist "yellow" and "red" together with the positive, black to the negative pole, and press the button to check if it boots. If it boots, the original car line is incorrectly connected or has a problem. If it doesn't boot, the unit is broken. Carefully check the wiring; do not blindly suspect the unit.
2. Automatic shut-down
- Cable 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.
- Unstable voltage: Find a 12V-5A power supply and re-test. If it doesn't shut down, replace the power supply. If it still shuts down, the unit has a problem.
3. Having noise
- Original speaker power too small: If the volume is turned up, there will be noise. When replacing speakers or listening to music, the volume should not be too high.
- Speaker cable grounded: Take the iron speaker cable and connect it directly to the unit's speaker cable.
4. Remote control cannot be used
- Test method: Turn on your mobile phone camera and align it with the remote control's light. Press a button on the remote control to see if the phone camera shows a light. If it doesn't light up, there's no power. Replace the battery. If it lights up, the remote control is working.
5. Settings cannot be saved (no memory)
- The yellow line and the red line are connected together (yellow to positive, red to key control).
- Yellow and red are reversed (just change positions).
6. Car audio with Bluetooth but it can't work
Operation steps: turn on the unit, use your phone's Bluetooth search, find the unit's user name, then click connect. After connecting, you can answer calls or play songs via Bluetooth.
7. Product smoke
If the product smokes, it indicates the internal circuit has burned, and changing the FUSE will not solve the problem. The unit needs to be repaired.
8. How to adjust the sound, equalizer settings
- Adjust the sound: Turn the volume knob to adjust.
- Equalizer settings: Generally, press the volume knob to display the equalizer SEL, and rotate the volume button to adjust each sound effect.
- Sound cannot be adjusted:
- Reset the unit or unplug and replug the power cord.
- The Volume knob is broken and needs to be replaced.
9. Reversing image is not displayed
- Wrong line or less wiring:
Camera connection method:
1) Find accessories (one camera + one power cord + one video cable).
2) Find the wiring port. First, locate the reversing control line on the unit's power line (pink or brown). Connect this line to the 12V positive pole, and the screen will turn blue. Find the CAME video input interface on the back of the unit, and locate the positive and negative of the backup light. Connect the camera: The red socket connects to the power cable, the yellow to the video cable. The red wire of the power cable and the video cable are screwed together to the positive pole of the reverse lamp. The black wire of the power cable is not used. The other end of the video cable connects to the CAME video input interface on the back of the unit. The red line coming out of the video line connects to the reversing control line of the power line. - Camera is broken: If the lamp connected to the camera does not light up, it is broken and needs to be replaced.
10. USB flash disk cannot be played
- Format the USB flash disk to FAT32, re-download songs, and try again. If it still doesn't work, replace the USB flash drive. If there's no content, download it again.
11. FM does not receive the program
- The antenna plug is not fully inserted, the antenna is disconnected, or the line is disconnected.
- To search for channels, hold AMS for 2 seconds. The unit will automatically search, or you can press the up and down buttons to search. If the above points don't solve it, unplug the antenna plug and use a screwdriver or metal strip as a temporary antenna.
12. No sound after installation
- Check if the speaker cable is short-circuited and connected. Reconnect if there is any short circuit.
- Check the number of speaker cables. If there are only two speaker cables, the original car line does not match the unit, and you need to re-route the original car line. One speaker needs two speaker wires; two speakers need four speaker cables.
13. No sound after a while
- Disconnect all speaker cables from the unit (do not remove them all), then find an external speaker to connect to the gray and purple wires of the unit's tail line. Connect any green group, and then check for sound. If there is sound, the car's speaker line is short-circuited or the speaker is damaged. If there is no sound, the unit is broken.
