2002 Tahoe Mirror Display

Does anyone know if the temperature display in the mirror of a 2002 Tahoe can be re-calibrated? It seems to be off by about 3 degrees. I have become very adapt at looking at it and subtraacting 3, but it would be nice to get it to be accurate. Thanks

No it cannot, only the compass but I did learn that when temperatures go above around 95, the temp usually is wrong, shows hotter than it really is, and also the best reading is when your driving about 60mph.

your suppost to be able to hold reset button down for 6 seconds it works for me on mirror left button
