IMHO:
Really like the new HVAC UI update. Better and simpler layout overall. The "Tab" outlining is visual helpful. The seat heat/cool display is larger, bolder and has click sounds to let you know when each level change is accepted and when you get to the end, the bars disappear! The Recirculate "button" is now easier to find and use - we also figured out how to use Google voice to turn Recirculate On and Off: Hey Google, Turn Recirculate On ; Hey Google, Turn Fresh Air On! Both work well and allow hands/eyes free quick change, especially when you see construction types of dust on the road ahead.
On the Blue Cruise front: it does appear to have brought some changes with it. 2.5 hour drive today on two Interstates (77 & 20) got more dropouts from hands free to hands on, then back to hands free - no road construction, lane markers, or detours in any of them. More lane ping-ponging at random times. The lane shift did seem to be engaging more often (good thing) when an oversized vehicle is on the right.
Bottomline, great move forward from Lincoln Engineering Software team. Funny though, I never get the updates at home (when connected to our WiFi), they always update while traveling and overnight away from home.... just an observation.
