In 2007 I purchased a VIZIO VX421L and am very happy with it. We use antenna only and the VX421L has the guide feature that gives us programming info. In 2012 I purchased a VIZIO E320VT for the bedroom but the "guide" feature does not work. I phoned VIZIO and they said that even though the guide button is on the remote, that the feature is not included. This makes it difficult to determine program information. Is there a way to make that feature work on the E320VT?
