Rear View Mirror Removal
Instructions in SI have been revised on servicing the Inside Rear View Mirror (ISRVM) assembly RPO DD8 on the 2005-06 Chevrolet Corvette. See document 1332917. The procedure has been revised for releasing the mirror from the windshield.
Remove the electrical connector from the back of the inside rearview mirror.
Rotate the mirror counterclockwise until an audible click is heard (fig. 16). Remove the inside rearview mirror.

To install, reverse the procedure. An audible click is heard when the inside rearview mirror is fully seated.
TIP: DO NOT pull rearward on the rearview mirror while removing or installing the mirror. Damage to the support or to the windshield may occur.
TIP: A slight movement of the mirror base from left to right is considered normal.
