I looked around the forums for a bit and couldn't find anything on this.

 

I live in Florida and temperatures here get really hot and I have a black car. I noticed a few times that the voice guidance and the menu selection beeps dont work and its usually during the day when its really hot.

 

Does anyone else have this issue? And if so, is there a way to fix it or turn it on after the cars cooled a little bit? If I reset it I have to put my setting back into it.
