My car is equipped with the BOSE High End Sound Package. The radio volume is supposed to adjust with speed and noise as detected by special sensors. This feature does not seem to work. I had my dealer check it out. They state that they hooked up a PIWIS Tester and checked for codes in PCM 2.1. No codes were present. They recoded GAL from level 4 to level 7. However nothing seems to be different. I still have to manually adjust the volume up when driving and then turn it down at each red light. By the way, I don't blast the radio; I'm talking about normal use. THX
