This has happened twice to me. The first time, turning off the engine and restarting it helped. This lasted a couple of weeks, then it went black on me again. This time nothing has been able to get it back. Been able to still use the hard keys for A/C, defrost, etc but no radio for now. Trying to find a solution I can do at home before I resort to taking to the dealer. I'm kinda skeptical on getting a FW or SW update. Going to try disconnecting the battery tonight when I get home to hopefully do a reset. Also want to try removing/replacing the fuse but I'm not sure which one to remove. Any info? Ive seen others have done that but there is no main uconnect system fuse, just separate ones for the radio, cd player, etc.
