SUBARU GENUINE
The knobs with numbers larger than 700 on exploded view are not
supplied for service parts because it is difficult to apply grease.
Please change to panel assy when you need repair to the knob.
The 6CD mechanism has not supplied repair parts for each part
(for Optical Laser pickup, motor etc). If you need repair to the 6CD
mechanism please change to mechanism assy (D40-2214-15).
