Android Head Units

1. Create a Wi-Fi hotspot on your phone and call it KYVNY5KL
2. Connect Head Unit to that Wi-Fi hotspot

Note: The hotspot name used to be 44FESRAN, although it stopped working in 2024 with an “UnActivated” error

Before making any changes, make sure you have a backup of your original file.

1. Use a USB drive with FAT32 formatted partition
2. On the root of the USB drive, create a folder called OEM
3. Copy your file into OEM folder, so that it’s accessible under /OEM/factory_config.xml location
4. Plug in the USB drive into Head Unit (if you have two USB connectors, use the one without CarPlay label)
5. You can now either start/restart the Head Unit to load the file automatically. You should see a toast message indicating that settings were applied.
6. Alternatively, go to Factory settings, “Profile Import” and tap on “Import Configuration” button to load the file manually.

1. Find out the exact version of your current MCU on your System Information screen in Settings
2. Find if there are any updates available on Discord where everything apart from a date is the same
3. Extract the ZIP archive if necessary
4. Copy the ksw_mcu.bin file directly to the root of the FAT32 formatted USB drive
5. Plug in the USB drive into Head Unit (if you have two USB connectors, use the one without CarPlay label)
6. Go to Settings, System Information and select MCU upgrade

1. Download suitable firmware OTA update (check Discord or forums for links)
2. Compare the file signatures with values from Updates page (if available) to make sure file is not corrupted
3. Copy the ZIP archive directly to the root of the USB drive
4. Plug in the USB drive into Head Unit (if you have two USB connectors, use the one without CarPlay label)
