I have a 1991 750iL with pictures of my dash on the E 32 home page. Look under pictures of Rods 750 iL

(not paradise by the dashboard light).

Just going through the learning curve with my 750iL.

To the immediate left of the radio, there's a hole, something missing from the dash. I looked in the owner's manual and it appears that there should be a vertical dial, similar to the one that regulates the dashboard light intensity. I see it pictured in the manual, but there is no description as to what it does. So, tell me what does this dial do? Thanks in advance for the help.
