@Patch Just to confirm, if you use the heated windshield function, you are saying it does not also blow air onto the windshield. So air will only go to windshield if in the main A/C controls you direct air distribution to the top, not if you press the windshield defrost button.I would suggest the heated windshield as well. Definitely $520 well spent. Even if the OP doesn't live in an area with lots of snow, it does a great job of defogging the glass when it's cold outside and damp/humid inside the car without having to blow hot air onto the windshield. It's an even greater benefit if you're often carrying passengers.
