❓ Frequently Asked Questions

🖼️ How to change the startup screen?
Before making any changes, we need to check if your CarPlay firmware requires an update.
Please go to Settings, locate “Firmware Version” under “Configuration”, and send us a photo of that information along with your Order Number.

📧 Our email: DC@yooomail.com

To change the startup screen:

  • Use a JPG image (1560×720 pixels) and name it boot_logo.
  • No need to add .jpg to the filename. Keep the file size under 120KB for best results.

Steps to update:

  1. Prepare a TF card and card reader.
  2. Format the card on your computer and copy the image to it.
  3. Insert the TF card after starting the device.
  4. The update will complete automatically once the boot logo is recognized.

🔄 How do I know if my CarPlay needs an update or has the latest firmware?
In most cases, a firmware update isn’t needed unless you’re experiencing specific issues.
If you’re having trouble or want to check for an update:

  1. Go to your CarPlay settings.
  2. Locate “Configuration” under “Firmware Version”.
  3. Take a photo of that screen and send it to us, along with your Order Number.

If an update is available, we’ll provide a link with:

  • Reference video

  • Firmware update package

How to update (4 simple steps):

  1. Prepare a 16–64GB SD card, the card software, and firmware file (from the links).
  2. Use PhoenixCard software to burn the SD card — just add the files as shown in the instructions and video.
  3. Insert the SD card into your CarPlay device to update the firmware.
  4. Restore the card using the software when done.

  1. Go to your phone’s settings and clear the WiFi and Bluetooth lists.

🔋 When I installed the CarPlay, it would not turn on.
Please check the following:

  1. Make sure the Type‑C connector is securely inserted — try unplugging and reinserting it.
  2. Verify that the B+, ACC, and GND wires are connected correctly.

If the positive and negative wires were accidentally shorted during installation, the device may have entered protection mode. In that case, disconnect power, reconnect the wires properly, and plug back in.

If it still doesn’t turn on, try using a USB cable to connect the device to a 5V 2.5A/3A wall adapter to see if it powers up.

Don’t worry — if the power cord is faulty, we’ll send a replacement. If the device itself is defective, we’ll replace it under warranty.

🔧 How to connect the three-wire hardwire kit cable (Red, Black, and Yellow)?

  • Red wire (ACC): Connects to accessory power (lights, blinkers, etc.).
  • Yellow wire (B+): Connects to the positive terminal of the battery.
  • Black wire (GND): Connects to a suitable ground point (e.g., a metal part of the vehicle).

🔄 It keeps rebooting.
Please try the following:

  1. Ensure the Type‑C connector is properly inserted — unplug and reinsert it securely.
  2. Confirm that the ACC lines are connected correctly and firmly.

Let us know how it goes. If the product is defective, we’ll replace it promptly under warranty.
