SO, someone needs to go into the control module with the computer and select which model the new control module is being used in. To expand just a bit, about the only difference in the climate control panel in the USA between the 210 and 202 is in the USA the 210 has charcoal filter, so yes there IS a difference, but in another country the 210 may not have charcoal filter, at least as a standard feature, so the control panel may be the same as the USA 202. Heck in some countries, believe it or not, air conditioning is even an option!
