Turned on cruise control. It worked but the steering assist (and the icon) did not come on. I had to toggle the steering assist off and on and the cruise control several times for it to work properly. And for good measure, I also toggled off and on the lane keeping aid. At some point during my commute, the collision warning beep and icon appeared on the instrument panel, so now I know my collision avoidance system works.Easy way to check if Collision Avoidance System is working properly try this. Turn on the cruise control on the steering wheel. If it does not engage you will get a warning "unavailable". If this happens your Collision Avoidance System is not working. Found this out yesterday. Electronics are somewhat quirky...you may not get the warning that the Collision Avoidance system is unavailable but cruise is disabled. Software issue...Good Luck...
It has been a weird experience with 2.3. Maybe it's because I also had to factory reset the AAOS after I upgraded to 2.3 that's causing the weirdness. I had to factory reset because I changed from iPhone 12 Pro to iPhone 14 Pro, and for some reason restoring from iCloud backup does not carry over Volvo credentials.
In any case, everything is working now. At least I hope so.
