Occassionaly i am driving and the car ups the temperature by three degrees. It was set at 72, i heard three beeps and it was at 75. I put it back at 72 and a few seconds later it went back to 75....do i have a ghost?

Also, sometimes it just starts navigating out of the blue. I wonder if they are related??

 

Is this confined to the temp control or are other aspects acting up?
