SatNav popup unit rattle noise

[step_change]

Hi all, Anyone got any ideas how to fix this? It happens over bumps, drain covers etc. More of a deeper "knock" noise than a high pitched rattle. Not a show stopper for me and I could live with it but would be nice to fix it if I could.

Appreciate any ideas please guys?

is it like on cold mornings when the unit opens and makes a crack as if the plastics stuck.

I used some silicon spray on the pivot points and its been silent since
