I've had an STS for 5 years that is supposed to recognize fob 1 or 2 when you open the door & adjust seats, mirrors, etc. automatically for the settings for that fob (like a XLR). This has NEVER worked since I've had it; I've always had to go into the nav & push "Driver 1" to get it to work.
We've taken it on its first long distance trip with my husband driving, but using my fob. After the first 3 stops, it has suddenly come to life & started putting the seats & everything where they are set for me when the door is opened.
It's fine if that wants to work now but what an inconvenient time!
Maybe now is the time to retry voice commands with it. All its ever done for any type of voice command you give it (whether for radio, A/C, whatever) is respond with "System defrost on" & turned on the defroster. If it works . . . I will miss arguing with it.
