After working for a while, the product suddenly cannot connect or be used. How can I resolve this?

1. Check that the USB plug is inserted firmly and fully to avoid poor contact.

2. Reset the car's multimedia head unit and connect again.

3. Press and hold the product's reset hole for 15 seconds, then try to connect after the reset.

4. Connect the phone to the device's Wi-Fi and go to the backend to check for firmware updates.

(1) Turn on the phone's Wi-Fi, search for the device's Wi-Fi (the Wi-Fi name is the same as the device's Bluetooth name, in the format CAR2-XXXX), and connect to it; the password is 88888888.

(2) After a successful connection, open the phone's browser, enter 192.168.1.101 in the address bar, and tap Confirm to enter the device's backend.

(3) Find the reset option in the backend and tap it to perform the reset. After the reset is complete, try connecting to the device again. At the same time, check on the same page whether there are available updates.
