Nope. Ive also been recently informed of this. Your FOB's have numbers on the back of them. 1 and 2. This works in conjunction with personalized settings.
Seat position, mirror positions, pedal positions, and radio presets and some climate controls.
Not necessarilly all AV's have the pedal, seat, mirror functions but all 03's have the same radios.
So as an example, if your significant other has a totally different taste in music they can preset the radio the way they want and you can for yours, and when you use your FOB it will remember which presets you have set up and the same goes for the number two FOB. Or you can set them the same. But thats what is going on.
