I just finished up an x930bt install on my 2001 Silverado, and I noticed that the outside temp reading in my rearview mirror is now about 10 degrees low. The mirror has the onstar, compass, and the temp reading. Not concerned about the onstar, but I know it has a wiring harness that connects to the back of the factory radio. Is there anything that I should have done, should not have done, while wiring this up that might have caused this?
I also stopped by the dealer today and picked up a new sensor just to see if that might be the problem, but it wasn't. Still reads about 10 degress lo
