Repair-It

Figured I'd start my own thread. This was mentioned on a Mercedes forum and seemed like it might OK for $180. I think I'm inclined to use the stock screen and control knob. I also assumed this could be removed if it failed and go back to stock functionality.

The one you linked was $50 cheaper.

I wonder if they're all made by the same manufacturer.

I think the guts inside are largely the same yes.
