Do you mind giving the part number of the cluster? You simply have to pull on it and it will "un-clip" from the dashboardI'm not sure what you mean by "easily found."
This is the Smart 451
Trip Computer (C18).
It came with the Cruise Control Package (P21), which also includes the
3 spoke leather steering wheel with cruse control (I47)
Cruise control package code (P21)
Cruise control (V27)
and cost me $280 as an added package on my 2013 Smart.
I don't recall if it was available independently of the package.
I'm reading from my own order a long time ago. I'm sure others here can better explain what all this means. I hope this helps a little.
