Android CarPlay Headunit ZLink App Update via USB

Job ID: 40145437

Budget: $30 – $250 AUD

My Mazda 6 (2011) aftermarket Chinese head-unit is running Android 13 and shipped with the ZLink CarPlay app. The unit doesn't connect to Wi-Fi networks.

What I need:
• Clear step-by-step instructions to install a clean, up-to-date version (or patch) of ZLink, installed via the USB port (as WiFi is unavailable)

I can supply any specific details of the aftermarket unit once we start.
