So today I noticed that the outside temp on the DIC read 59 and the center stack said 60. This made me think that there could be two independent outside temp sensors. Has anyone else ever seen this scenario?

hope I'm not out of line here but is it possible you are reading the outside temp and inside climate temp setting?

They both say "outside".

OP, that's weird. I've never observed this in my GX. I wonder why it's showing two temps.
