Has anyone noticed that their attitude display fades out around edges after the truck has sat in the sun for a couple of hours (temps above 95F)? No starting problems, just hard to read the display. Goes back to normal as the cab cools down from the a/c.

there are some threads about this in the LLY Electronics sections.. display blanking out and stuff.. don't know at this point if its heat related.

I noticed the mount that holds my Attitude is VERY hot, but I've not yet seen any issues.

Just send it back to edge. Give them a call and they will take care of you. I had the same problem, but not heat related. It just blanked out from time to time.
