From pg 135 of the owner's manual (pg 427 for MyFord Touch):
Spd. Comp. Vol. - Automatically adjusts the volume to compensate for speed and wind noise. You can set the system between 0 and +7.
0 means off and 7 means highest automatic volume adjustment according to vehicle speed. My salesman set mine to 3 and suggested it's the best setting.
As for the HD radio signal, when mine connects, it only seems
a little bit louder because it sounds a little bit clearer. Perhaps it does get a little bit louder too. /shrug
