This is my gripe. I want a HUD because I find it safer to not have to look to the side to see how fast I'm going. Also, the HUD has Android Auto, So I can look at a map in a safer manner. I don't have to have a HUD, but I prefer it. I don't need AC either, but I like having it. My only option was to use a 3rd party product. Tesla makes software changes without notifying their partners and giving them time to handle it. What other car company does this? it would be like if GM had made a software change and then all radios that weren't AC Delco stopped working. There would have been outrage. But since we're used to Tesla having terrible support, we accept it and blame the consumer.
