It consists of a GS-911 USB interface for PCs with a USB connection and the GS-911 diagnostic software. It is a useful helper and emergency tool on any trip. Check your BMW's control units independently. Read your error codes yourself, because if there is a problem, the nearest workshop is often far away. With the help of the GS-911 USB, you can independently perform repairs, service work, basic settings, retrofits, and special requests on your BMW motorcycle. Many diagnostic functions can be carried out at nearly workshop-level quality.
