Question About 'Speed Compensated Volume' on Bose Sys
I have a 2LT coupe which comes with the Bose 10 speaker system. I have tried without success to locate the 'speed compensated volume' controls or their Bosian equivalent in this system. Yes, I have read the infotainment manual p. 12 where it talks about 'auto volume' and 'Bose Autopilot'. I've turned on Bose Autopilot which seems to do nothing. 'Auto volume' would seem to be what I'm looking for but it doesn't show up on any menu. Anyone have any suggestions?
Thanks!

Bose Audiopilot is the current version of/replacement for speed compensated volume. It uses a microphone in the cabin to sense noise (mic picks up both the audio system output and ambient noise and system determines which is noise), volume is then increased as necessary.
Does it work, I guess. I was used to the older SCV which has noticeable steps in volume and with my 2006 GMC diesel pickup the steps from SCV are very noticeable. When I bought a 2008 CTS it used the audiopilot system and it does work but it is far more subtle and as noted in the manual it is most noticeable at low volume levels. So I think two things are going on: 1. you won't hear the big steps in volume that you are used to with SCV since the gain adjust is continuous rather than the 3 or 4 steps of most SCV systems. 2. My CTS manual states clearly that audiopilot is only effective at low volume levels and no adjustments will be made once the sound level is high. I don't know for sure but I bet some of this is due to legal concerns of advancing an already loud level too high (as in causing ear damage AND preventing the operator from hearing emergency vehicle sirens).

I am pretty sure you get either one or the other but not both choices. The lower cost system (1LT) gets SCV while the higher end system (2LT/3LT) gets audiopilot. At least this is the what I have found with other recent GM vehicles. I am holding off for the Z06 so I have not spent any time in a C7 but I have found in my other vehicles with the enhanced Bose systems I am happiest with both audiopilot and "center point" turned off, the latter is really annoying to me and its impact on tonal balance is extremely obvious on high quality recordings.
And as you have noticed audiopilot is of little use, well actually a little. I had audiopilot turned on when I first bought my CTS and one person I work with speaks very loudly and it would turn up the radio volume whenever she opened her mouth which was pretty funny.

Your "either or" comment would explain why I can't find 'auto volume' in my system. The manual does say "if so equipped" so it's probably referring to the 1LT. I've been dialing Kenwoods up and down for years and was really looking to having SCV in my Corvette. This is the first negative I've found in the car. I would question the thinking of equipping a Corvette with such a system, given its selective exhaust note and top down features. Well it just goes to show you how hard life can be here in America

I suspect this sets me straight, thanks!
