Since yesterday evening I am having issues with my car. I appear to have a valid LTE connection as my Google Maps are updating. But when I go to play music via Slacker or Tunein it downloads the Track Name and the Album Art but then it says "Unable to Play" right under the line that shows the track download progress and timeline. The voice command button doesn't seem to do anything either. And the browser doesn't seem to want to update. I tried to switch to Wifi using my iPhone as a hotspot but that doesn't change anything. I have rebooted three times by holding down both scroll keys. But that hasn't helped. Are there any other types of reboots that I could try, like a harder reboot?
