We've been enjoying our '14 Summit and ran into an issue with the Speed Compensated Volume control..It just doesn't seem to work despite any setting (off 1, 2 or 3) we choose. We constantly play with the volume control and in stop/go traffic it is a PITA. Maybe the effect is so subtle that it isn't perceptible
My GM truck has this feature and it works very well in this regard. Any others share in this issue?
