I used to think this. But the quality and integration of the infotainment in new cars, for example Tesla, is so much better than any extern unit I have tested, that now I really appreciate the systems coming with the car.

I used to change the unit, amp and all speakers. Now my new car is just working nicely unmodified.

Keyword being new. What happens in 3 years? 5? 10? Will the manufacturer keep it up to date?

1st-gen Tesla are now 11 years old(first production is 2012). We already have answers and direction of motion; they won't bother engineering replacement screens for decade old cars, and they happily assist you with buying more cars when you think your gigacast has a hairline.
