CarTrimHome C12 — WiFi Keeps Turning Off? Here’s What to Check

Normal Behavior with Wireless CarPlay

When Wireless CarPlay is enabled, the C12 WiFi may automatically turn off.
This is caused by Apple’s Wireless CarPlay limitations and is considered normal behavior.


If WiFi Repeatedly Disconnects

If the WiFi reconnects and then quickly disconnects again during use, please check the following:

  • Make sure the Carlink app is not running in the background.
  • Completely close the Carlink app and test again.

This usually resolves the issue.


How to Keep WiFi Connected While Using CarPlay

If you want the C12 WiFi to remain connected while using CarPlay, try this method:

  1. Connect your phone to the C12 USB port using a USB cable.
  2. Turn OFF Bluetooth on your phone.
  3. Open the Carlink app.
  4. Start CarPlay using the wired connection.

With this setup, the C12 WiFi connection can remain active while CarPlay is being used.
