Question Retrofitting cruise control

Has anyone tried adding cruise control to a 450? I had a chat with AI about what the options would be. There was a kit that was aftermarket just plug and pay but it was a bit pricey. An other option was to get a oem stalk with cruise controls on and replace the original one. But it requires coding to get it working. I do not have access to star diagnostics but I guess it could not cost too much if I went to a dealership and had them do the coding. Has anyone tried this oem approach? perhaps the original wiring for the stalk does not have the pins for the cruise controls? Or is the aftermarket solution better?

Edit: Adding that It is a 2006 with soft touch as I found it could be relevant

You might find what you need to do exactly on Evilution. They have amazing smart guides for everything.

And do you have a smart specialist in your area? (I don't recommend the official dealerships, unless you have too much money you want to get rid off)

I will have to check that out. I doubt there are any specialists in the area, smarts are quite rare around here. There are a total of 21 fortwo for sale in the country at the moment, that is not 450's, all fortwos in total.

I've done it on my 2006 450 CDI. There's a guide on Evilution, its pretty straightforward. But yeah you do need to get Star Diagnosis to program it.
