Comfort Access - how does memory work?

[Ferguson]

I have a 2007 with comfort access and newish software (just took delivery).

It works. Mostly. But the manual instructions seem to differ from the dealer's instructions, which differ a bit from reality (which seems a bit random).

Specifically: the dealer said to memorize a setting, you (a) must have the key in the slot, not your pocket, (b) press the M button, then (c) press "1" (regardless of which key you use, always press "1").

Seems to work, most of the time. The manual doesn't indicate a need to have the key in the slot. So first question -- does the key have to be in the slot, or just your pocket?

And if not in the slot, then when does it memorize -- do you have to press M+1, or is the act of changing it when using the key enough?

And is it really M+1 for both keys?

Next - it doesn't always work. My wife's was working fine, then about 4 days went by and we went out together, and it didn't do anything when she opened the door. I checked her options, it was HER options (she keeps the unlock to driver's side only, mine is all), but the seat didn't move. So we went through the whole thing again, saved it, and it worked the next day.

Maybe the car is lonely and only remembers you if you drive every couple days? Other theories?

Next - is it supposed to remember the current station tuned in the radio, or just the presets? I need to experiment more carefully, but it seems to SOMETIMES reset the current station, sometimes not. Though perhaps this comes back to the question of when it memorizes a setting -- all the time (last setting), when you press M+1, when you put the key in and press M+1?

Finally -- how does memory work with the PASSENGER side? Does it work at all, or is that one strictly the M+1, M+2 setting and you push the button?
