The S80 is not idiot proof. Perhaps Volvo figured if the S80 is not garaged there is no reason to program the Homelink. Therefore no security issue.

Gee, thanks. I'll check and see if my '96 has that handy connector when I get back to playing with it this weekend. Good thing to know about.

2002 2.9 S80 - Wife's car, the "Silver Flash"
1996 855 Turbo - Formerly daughter's ride. My toy now.

Former Volvos:
