It seems D,E,F (and any later letters) get v. 17xx, while Blank,A,B get v. 16xx. So your teory would be correct. However, i dont get why the first ones dont get the option of connecting wirelessly to AA. As far as i know, there is absolutely no difference in the hardware need for AA vs Carplay, and wireless carplay works flawlessly... I really think Seat should take this into consideration and release the wireless functionality for AA as well.
Well, it looks the same. It didn't even move my preferred shortcuts in the bottom line of the screen. So... not really. I did however get an update to the Kessy system (i think this is separate from the infotainment computer system) which is absolutely perfect. I might even forget i have a key in my pocket now.
I asked them to address a number of smaller problems like the AA sound suddenly not working, some yellow door warning showing up at random, incorrect profile loading, and not being able to control the temperature if its too cold outside... I will have to drive the car for some time to verify that this has actually been solved. The mechanic told me they were, and informed me that a lot of other smaller issues should be resolved as well with this mayor update package.
