Thanks to all for all the great info on the Ungo 8300. Had mine installed yesterday,nice alarm. During install the driver window stopped going up on auto when pressed hard. After the installer called a BMW tech we found out that the windows have "memory" and simply forgot what it was supposed to do. To correct press and hold the down button for 5 to 10 seconds after the window is all the way down; then repeat for Up. The window will then remember the Auto setting.
