3. Installation
3.1 Pre-Installation Check
Before proceeding with installation, it is crucial to confirm your car's audio input options. The Android sound is transmitted through either AUX or AMI.
- If your car has an "AUX IN" hole: Use the "Audio out" cable on top of the Android ISO power cable to plug into the AUX IN hole and get sound.
- If there is an "AMI" port in your car: You must use the "Audio Out" wire on the top of the Android ISO power cord to plug into the AMI cable and then into the car's AMI port to get sound.
- Note: If there is no AUX or AMI on your car, you will need to add an FM transmitter to produce audio. However, the sound quality will not be as good as AUX or AMI. Please acknowledge this issue before placing the order.

3.3 GPS Antenna Installation
Proper installation of the GPS antenna is crucial for accurate navigation. Follow these steps:
- Location: Recommend installing the GPS antenna on the dashboard or rear shelf.
- Placement: The antenna should be installed on a leveled surface facing the sky to minimize blockage of radio waves.
- Obstructions: Vehicle equipped with tempered glass or tint may weaken the receiving signal. In such cases, consider installing the antenna outside the vehicle.
- Preparation: Before affixing, clean the designated surface thoroughly.
- Mounting: Tear off the backing of the tape and firmly press the GPS antenna into place.
- Cable Routing: Remove the side cover of the car interior, move the cable through the storage box until it reaches the control panel of the machine. Secure the cable with a cable tie.
- Connection: Connect the GPS antenna's plug to the machine.
Notes:
- Ensure the system power is off when connecting the GPS antenna.
- Do not shorten or extend the GPS cable. Altering the length may result in short circuit or malfunction.
- Do not interfere with the GPS antenna with the steering wheel or gear lever, as it may be dangerous.
