The Remote-Control Feature




Unlike the BMW On-Board Computer I, most functions can be called up by remote control. Each display can be shown, in sequence, by pushing the turn signal lever in toward the steering column. The display will change sequentially from left-to-right and top-to-bottom for each push inward of the lever.

The Code function is skipped over when using this method of changing displays.
