TMMAR, IMO if the adjustments are not noticable and you feel the volume level is still good (wereyou would like it), then it is working well, I have this feature in a Suburban (just a turn dial on the volume knob) and it is a much more noticable adjsutment in volume, sometimes I need to turn the volume down whe it adjusts. I just think they have refined or tuned the controls much better than they were in the past.TMMAR said:johnway,
I do not have a navigation system- only the XM radio and have set the speed compensation volume to high. I too find it very hard to discern any increase in the volume which is why I'm not sure it is working correctly. The reason I say this is because I had an '02 Envoy with the same feature and the increase in the volume was more noticeable.
As a personal aside, how are things in NE PA? Both sets of my daughter-in-laws grandparents live in NE.
