In reading past posts, it seemed like there were complaints of the Model S only having 11 volume settings... In my P85D, I noticed that before the number increases, I have 2 or 3 presses of the button/changes of volume (this was likely using the steering wheel button, don't think I used the onscreen buttons). Was it true that it only had 11 settings before, and thus is this a welcome little improvement that there are now ~30 settings for the volume?
