Audio Streaming Mode: Adjusts the decoding protocol and transmission stream method for the audio signal transmitted from the box to the original car's infotainment system.

● Sound Abnormalities/Noise: Resolves stuttering, electronic noise, popping sounds, or intermittent playback when playing music or navigation audio.

● No Sound: Resolves issues such as no sound when playing music after connecting to CarPlay, or the car's infotainment system not responding when switching songs.

Audio Latency: Buffering time of the entire audio buffer.

● Audio-Visual Desynchronization: Resolves the issue of "lip movements/images not matching audio" when watching videos or receiving navigation voice prompts.

● Frequent Audio Stuttering: If the car's Bluetooth/Wi-Fi anti-interference capability is poor, increasing the audio latency (increasing the buffer size) can sacrifice a small amount of real-time performance for smoother playback and reduced audio stuttering.

Startup Delay: Sets the box to delay for a specified time (e.g., 3 seconds, 5 seconds, 10 seconds) after startup before sending a CarPlay communication signal to the original car or attempting to establish a connection with the phone. Some original car stereos start slowly. If the box sends a signal too early, the car stereo may refuse to connect before initialization is complete, resulting in a black screen, a "USB device not recognized" message, or an inability to connect. Setting a startup delay allows the car stereo to fully power on before establishing a connection.

Hotspot Band: Change the Wi-Fi hotspot operating frequency of the adapter. Try different frequency bands (36/40/44/48/149/153/157/161) to try and resolve issues such as audio stuttering, video stuttering, pixelation, and frequent disconnections.

GPS: Determines whether the system prioritizes the phone's own GPS chip or the box/car's GPS chip during navigation. When the car's GPS signal is weak, or the GPS data transmitted from the car stereo to the box is inaccurate, disabling this option (using the phone's own GPS instead) can resolve issues such as inaccurate navigation positioning, route drift, or GPS loss.

Forced Display: Forces the output image resolution, aspect ratio, or frame rate of the box to match the original car screen, bypassing the car's original EDID resolution handshake process.

Black Screen/Screen Distortion/Stretching: Some modified car TVs or vehicles with special screen widths may experience black screens, severely distorted or stretched images, or large black borders after plugging in the box. Enabling "Forced Display" can correct the screen ratio or force the screen to light up.
