I just had my Emira in for warranty “software updates”. One took several hours and the other was the most recent update, which was quick. I asked the tech what they did and was told everything related to improving security, to make the systems less hackable. He said the car software is inter-related so changing one area required others to be changed too; hence the lengthy update. He also said most vehicle manufacturers were doing similar updates, as hackers get more sophisticated and vulnerabilities are identified.
I’ve since noticed no change with my KEF however I’d already modified it by adding the 2 Alpine tweeters, the 10” Kicker sub-woofer and sound insulation.
