Hi,
Its the latest model GS911 Wifi i bought it 5 days ago.
I registered the device and also registered the VIN for my bike.
The problem is already solved. But maybe its nice to know for people in the future.
When connecting by Wifi it doesn't show my Vehicle electronics, then i tried to connect via the USB and it immediatly showed the vehicle electronics.
So i think the wifi connecting wasn't stable enough to make a good connection.
Thanks for the reply
