I have tried to alter the external temperature display to Farenheit on the EVIC by changing the settings from metric. Doesn't do it. Any ideas?:confused:

Strange? My EVIC switch between US & Metric with no issues? Where are you located?

Mine's works just fine and I am in the US. Try changing it from metric (to English is it? - Don't remember how the EVIC calls it), turn off the vehicle allowing for at least 15-20 seconds before turning back on again.If still in metric then I would suggest going to the dealer and have them check it out.
