It seems like there must be a fuse on this, but I don't see one
mentioned on any of the fuse covers or in the manual.
I managed to knock the cover off the unit in the trunk-- and then to
turn a corner just right so a can of soda exploded on the exposed
sharp metal pieces. Soon after I noticed I didn't have Onstar.
I'd like to replace the fuse first before I take it to the dealer for
