- pilot assist (just activate)
- electric front seats ( driver with memory, passanger without)
- electric folding rear headrest
- semi automatic parking
- front fog lights
- bliss and CTA
- keyless entry (with foot movement sensor for trunk)
- homelink
- adaptive headlights
- harman kardon
- illuminated sills from 90 series
- steering wheel padlle shifters
- headup display (with cutting dash)
- rear  camera washer (custom made with 10 euro )
- sport body kit from volvo accesories
-s90 armrest + knee rest for center console
- rse by key (only activation)
 - polestar software (at the dealer)
- aluminiu engine shield (from accesories)
And i think there are more, but i can't remember.
If you need info, i will answer

I have a question about the illuminated sills from the x90. I do have them also, but I had to disconnect the footwell light from the passenger seat to keep them on. They would not stay on if I kept this one connected. Did you see the same thing or did you connect them another way?
