climate control reading celcius

I just bought a 99 gtp :iceslolan . The only problem I have is the dual climate control is reading celcius temps :eek7: . it works correctly but I don't know how to get it back on farenheit. the eng/met button on the dash display has no effect. Anyone have any ideas?

There used to be a site that I believe had instructions for this.

I just remember that when the fans are off, hold the driver and pass buttons down at the same time. The readout will change to 00 and then the driver dial is used to change options. That might be what u have to do to change it, but Im not 100% on this as Ive never had to.

Try www.clubgp.com someone over there might remember or know how to.
