4.1. Pre-Installation Test
Before installing the unit in your car, connect it to a 12V power supply (e.g., a car battery or a 12V power adapter) to ensure it powers on and functions correctly. This helps identify any issues that may have occurred during shipping.
4.2. Universal Machine Power Cord Wiring
The universal power cord comes with loose wires. You need to identify the wires corresponding to each function in your vehicle's wiring harness, connect them, and insulate them with electrical tape.

Ledningsinstruktioner:

- Identify Power Wires: Use a multimeter or 12V tester to find the following in your vehicle's harness:
- Battery (+12V Constant): A wire that shows 12V when the key is in 'LOCK' position. Connect to the Yellow (BATTERY) wire of the player.
- Ignition Switch (ACC): A wire that shows 12V when the key is in 'ACC' position and 0V when in 'LOCK'. Connect to the Rød (ACC) wire of the player.
- Jordledning: Tilslut til Sort (GND) wire of the player.
- Illumination (ILL): A wire that shows 12V when headlights are on and 0V when off. Connect to the Orange (ILL) tråd.
- Reversing Camera Control Line: Tilslut til Pink (BACK/REVERSE) tråd.
- Ratstyring: Opret forbindelse til Brown (KEY2) og Orange/black striped (KEY1) ledninger.
- Auto Antenna Power: Tilslut til Blue (ANT) wire (12V+).
- Højttalerforbindelser: Connect the corresponding speaker wires (White, White/black striped for Front Left; Gray, Gray/black striped for Front Right; Green, Green/black striped for Rear Left; Purple, Purple/black striped for Rear Right).
4.3. Special Vehicle Power Cord
For vehicles with a special power cord, simply plug the player's socket into the original car plug. If your vehicle uses a CANBUS protocol box, connect it to the 8-pin position of the host. Note that power cord plugs and CANBUS protocol boxes may vary by brand.
4.4. Reversing Camera Installation
To install an optional reversing camera:

- Connect Power and Video: Find the accessories: 1 camera, 1 power cord, and 1 video cable.
- Locate Wiring Ports:
- Find the reverse control line on the unit's power line (usually a pink wire). Connect this line to the 12V positive pole, and the screen will turn blue.
- Locate the CAM video input interface on the back of the unit. Find the positive and negative terminals of the backup light.
- Kameraforbindelser: The camera typically has two connectors.
- Connect the red wire of the camera's power cable to the 12V positive pole of the reverse lamp.
- Connect the yellow video cable to the video input.
- The red wire from the video cable should also be connected to the reverse control line.
- The black wire of the camera's power cable is usually not used.
- Skærmindstillinger: Some models adapt to the camera's resolution automatically. Others may require manual setting of the camera's resolution type in the unit's settings for the image to display correctly.

- Kabelfejl: If the blue cable (automatic antenna power supply) is connected to the unit's power cable, it will automatically shut down. Correct the wiring.
- Ustabil Voltage: Test with a stable 12V-5A power supply. If it still shuts down, the unit may be faulty.
6.3. Noise Issues
- Low Speaker Power: If the original speaker power is too low, noise will occur when the volume is turned up. Reduce volume or replace speakers.
- Jordet højttalerkabel: If the speaker cable is grounded, connect it directly to the unit's speaker cable.
6.4. Fjernbetjening virker ikke
Test by pointing the remote at a mobile phone camera and pressing a button. If the phone camera shows a light, the remote has power. If not, replace the battery.
6.5. Settings Not Saved (No Memory)

6.12. No Sound Immediately After Installation
This is usually due to a wiring error or a short-circuited speaker wire. Check the speaker cable for short circuits and reconnect. Verify the number of speaker cables matches your original car wiring; if not, re-route the original car line. Each speaker requires two wires.
6.13. No Sound After A While
Disconnect all speaker cables from the unit. Connect an external speaker to the gray and purple wires of the unit's tail line. 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 faulty.
