Firmware version v1.6.0 will update over-the-air to your scooter. This version contains smaller fixes and underlying work, which will be used for a bigger app update later this spring. However for now you will not notice any changes on your scooter.
If your scooter is in hibernation mode the new firmware version will download and install when you decide to turn on the scooter again.
P.s.: You can always find out whether your scooter has already received the update and which version you are running with the help of the version box. This appears on your display when you hold down both brake levers for at least five seconds in parking mode.
