I did it on my '10 XC60 T6. Works very well! You'll need the 2 additional wires (if you have a computer case fan handy, the pins from those fit, it what I used.)
The Adaptive Cruise Control issue has been fixed, so no issues there.
I believe the DSTC is not able to turn turned off with the TFT dim though, as in those cars, the option is in the Sensus settings, not the DIM.
