It’s a very logical chain - aux heater is one of the best options on xc90 - I use mine all the time for about 7 months a year. If you accept aux heater as a no brainer then heated screen is redundant. Add to that that wires can be spotted in the windscreen. HUD is a safety feature - it lets you keep an eye on the road instead of peeking at the dash and refocusing (you only realise how much more tiring it is to use the dashboard when you are used to hud).
