Just put my Delphi TNR in last week, I assume the date is updated with gps. I don't have gps antenna module yet, is there anyway to change the date manually, shows dec 31 2009. Also I have heard there is a way to access the internal data menu by pushing two buttons together, does anyone know the inner workings of this unit. Thanks.

Did some searching, finally found a way to enter diagnostic menus and adjust the date and a lot more. If anyone wants to play in the diag. menus post here.
