2010 Mazda 6 iTouring: temperature display suddenly switched to centigrade. Any idea on how to change back to Fahrenheit display? Thank you.

 

Thanks to Roger L. (in another forum). His solution worked perfectly. For those interested:

Page through the trip odometer positions. Just before the "A" odometer comes up you will notice the centigrade symbol flashing. Hold down the odometer button while the symbol is flashing and it will switch to fahrenheit just before the trip "A" mileage comes up.
