I have a 2012 RAM 2500, 5.7L HEMI. I have paired multiple iPhones to my uConnect system over the years with no problem. About 4 days ago, Uconnect simply stopped working. When you press either the Uconnect button or the phone button, all I get is an error message on the screen that says 'Uconnect not available'. The system will not allow any reset voice commands or anything else. Has anyone else had this issue? Is there a reset procedure? The Uconnect customer service site gave me a couple of reset options that didn't work. Any help would be appreciated. Thanks.
