I guess I'm spoiled by my Cardo G9 and the Q2 I had previously. They both had an auto volume function that raised or lowered the volume from a base setting that you chose, based on the amount of ambient noise. Sitting at a light the volume would auto lower. As your speed (and noise) increased, the volume automatically increased. This should be a software mod as all the components are in place for this to work. Please consider this. I didn't realize the Sena units didn't have this before I bought them...With the other issues reported I would have waited a bit before buying these had I known.
