W140 Bose System
 

After a good inspection of my S320 it appears that I do not have the Bose System installed. If it was there originally it is not there now. I also cannot see the centre speaker at the rear view mirror. What other options were available at the time for a 1994 S320 euro version. Currently visible speakers mounts are , Front doors, 5in and 3in grills, rear doors 3in, rear shelf one cover each side showing outline of two 5in speakers either side. No mention of Bose visible anywhere in the car
