Hi! Would not believe this was possible... but it happened!

My kid placed his thick silver necklace on the instrument panel just before we drove bumpy road and suddenly... I noticed it diving in the vent channel in the middle of the dashboard on the instrument panel. Patient is XC90 2017 D5 R-Design.

I have tried to allocate it by removing the cabin filter in case it landed all the way down. Removed air intakes and used endoscope camera but all this without success. Have not been able to even allocate where it is.

Have anybody experienced such and how did you fix it? Any illustrations available how the air canals are placed in the car so I could check where it theoretically might have gone? Next is small vacuum hose connected to vacuum cleaner and randomly trying to see if it reaches something.

Any advice welcome!

Cheers!
