I wanted to set clock (I thought such a speedo has the clock) and pressed there until I changed everything. I no longer know how original condition was. I didn’t find clock. But speedo shows wrong speed. I’m proud. I downloaded so 10 manuals, German and English, I also have manuals at home where nothing stands. Manuals don’t work with me. I just can’t find the right combination. Maybe someone knows how to set this? rdere Felge is 21″ rear 18″. Year of construction 2010 Yes I know I’m not very smart. I can’t get any further on my own. Thanks
