One question I have had - I assume the A/C quits blowing cold air - is this correct? BTW, I'm glad the 550 does not have it yet.
It saves quite a bit of gas if you sit in Houston traffic. Or DC traffic. Or LA traffic. Etc. If you don't sit in traffic, it's plain annoying.

I've had two loaners with it and enjoyed having it around town, not so much on the highway stop and go. It was nice to see the MPG number not move at all while at a light.

Yes, it does turn off the compressor. However, the air is still cold. If the cabin temp gets too warm, the engine will restart.
