Changing Readout from C to F on Heat Display?

[Spasso]

Am I stuck setting my heat by centigrade? I haven't seen any references to changing the readout to fahrenheit in the owners manual.
Thanks, DJ

People keep thinking I'm talking about the OBC EXTERNAL readout.

I am talking about the digital INTERNAL readout above the OBC

The INTERNAL heat is set at 20.0C----20.0C. How can I change this to F

Refer to the pictures. Any deas.

The equation for converting Fahrenheit to Celsius is:

((Deg. F) - 32) x (5/9) = Deg. C

I have been told by an E46 guy that on his car you press the "Auto"(heat) and "Forward Defrost" buttons at the same time to change the scale readout. Both of these buttons are on the heat display panel not the OBC.

I won't be able to try this out for about 8 hours. Someone want to give it a try?

The E46 reset method didn't work
