The product suddenly stopped working after several months of use. How can this be resolved?

Regarding the CP82 suddenly stopping working after several months of use, please follow the standard procedure below to reset and restore it:

1. Hard reset of the device: Make sure the device is properly powered on and plugged into the vehicle's USB port, find the hidden button on the device body, press and hold it for 15 seconds, then release it. At this point the indicator light will blink white. This operation is specifically for when the device stops working after some time of use; it can effectively clear the internal connection cache and force a system restart.

2. Clean up and reconnect on the phone: After the reset is complete, it is recommended to clear the Bluetooth and WiFi connection history on your phone and restart the phone. Then turn on the phone's WiFi and Bluetooth, find the name that matches the device in the phone settings or the head unit's Bluetooth list to pair, and accept all system prompts to reconnect automatically (after a successful connection, there is no need to pair again on the next startup). Note: If you need to connect a second phone, you must first disconnect the currently connected phone.

3. Backend upgrade troubleshooting: If problems still occur after the reset, you can enter the device backend through the LAN tool to update the firmware. Connect your phone to the device's WiFi (the WiFi name is the same as the Bluetooth name, and the password is 88888888), enter 192.168.1.101 in the browser address bar to access the backend, scroll to the very bottom, tap “Update”, and wait for it to finish. **For iPhone users, reference video: How to upgrade the wireless adapter through iPhone
