Hi friends,
I'm Amy from OTTOCAST, thank you for shopping with us.
The video is about the steps of U2-AIR online upgrade. If there is a problem with the product, you can upgrade first.
Please feel free to contact me (service@ottocast.com) if you need any technical support.
U2-AIR online upgrade method:
1. Connect the U2-AIR to the car USB port (preferably plug into the power source of the charging head)
2. If U2-AIR is successful, the following steps can be ignored. If the car screen displays the interface that the bluetooth signal is always on, for example: BT device: AUTO-****, you need to manually turn on the WIFI of the iPhone and connect the WIFI of the device: AUTO-* ***
3. After connecting to WIFI, log in to the website: 192.168.1.101
4. After entering the upgrade interface, click Upgrade. The blue light of the U2-AIR will keep flashing. After checking the progress bar for a successful upgrade (about 2 minutes), wait another minute. After the device is successfully upgraded, the blue indicator lights up. Be sure to observe the U2-AIR's LEDs to ensure the upgrade is complete before unplugging the device.
