(This thread seems like it may now better fit in the Infotainment section)
Just upgraded to .335 myself. Other than the 3 minute wait for the system to turn off completely as part of the final install steps, I haven't really let my car sit for hours and then tried it, but so far the response time seems significantly improved in many ways. The boot logo comes up and goes more quickly, and the disclaimer now actually goes away immediately if I click the screen or use the Command knob. The system recognizes an attached phone and more quickly goes into CarPlay than before. This were all rather slow to react with the .100 my car came with from the factory.
All anecdotal, your mileage may vary, blah blah blah, and of course I'll need more time with it just to see how the system now responds to last use CP/this use BT or vice versa, and just general switching between the two speed-wise, and if it better remembers last usage source overall instead of always defaulting to radio.
Again, a reminder that if you have done any of the so-called tweaks, my understanding is that this removes them and blocks both any existing ID7 persistent workaround installation and also apparently the last remaining ability to use the serial port connectivity for further tweak installation. So, essentially it locks the system out from existing or new tweaks installation. Since the only one I really got used to is the active touchscreen while driving, I'm going to deal with just using voice or the Command knob for usage while driving, and hope that someone finds a way to again at least implement the always active touchscreen. To be honest, the lack of active touchscreen isn't that big a deal for me, as I always used a weird mix of touch, Command and voice functionality anyway in my 2016. I think I only used touch while driving when whatever required a single touch--if more, I tended to then default to the knob or voice.
